Download Article Download Article If you’ve written or downloaded some C code on your Windows PC, you’ll need to compile the code to turn it into an program you can run. This simple wikiHow tutorial will walk you through compiling and running a C program from the Windows command prompt using MinGW, an easy-to-install version of the GCC compiler.

  1. 1 Install MinGW, a simple C compiler. If you haven’t already done so, you’ll need to install a C compiler on your PC to compile the C program, Compiling the C code will turn the code into an executable C program. MinGW is one of the easiest options to install for Windows:
    • Download MinGW from https://sourceforge.net/projects/mingw,
    • Double-click the downloaded file and follow the on-screen instructions to prepare the installation.
    • When you get to the MinGW Installation Manager window, you’ll see several packages in the upper-right panel.
    • Check the boxes next to “mingw32-base” and “mingw-gcc-g++.”
    • Click the Installation menu and select Apply Changes,
    • Click Apply,
  2. 2 Add the compiler’s path to your system environment variables. This step makes it easier to run the compiler from the command prompt, as you won’t have to enter the full path to the GCC program.
    • Press the Windows key and type environment, Click Edit the system environment variables in the search results.
    • Click the Environment Variables button.
    • Select the “Path” option under “System variables” and click Edit
    • Click New,

  3. 3 Open a Command Prompt window as an administrator. To do this, press the Windows key, type cmd, right-click Command Prompt, and then select Run as Administrator,
    • Once the prompt window is open, double-check that the compiler installed properly (and that the environment variables are set) by running the command gcc – version at the prompt.
    • If you already had a command prompt window open, close it and open another so the path you added
  4. 4 Use the cd command to go to the directory where your C program is saved. For example, if the program you want to compile is in C:\MyPrograms, type cd C:\MyPrograms and press Enter,
  5. 5 Run the gcc command to compile your C program. The syntax you’ll use is gcc filename.c -o filename.exe, This compiles the program and makes it executable.
    • Replace filename.c with the name of the file containing your C code, and filename.exe with the name you want to give the compiled program.
    • Make sure you give the compiled program a name that ends with,exe,
    • The -o flag specifies the output file.
  6. 6 Type the name of your new program and press ↵ Enter, For example, if you created a program called hello.exe, you can type hello or hello.exe, This runs your C program from the command prompt.

How do I run a,C file in root?

    How to run c/c++ files on root I have tried writing codes line by line but it’s too much work and I want to know how to write in a text editior and run it on root then as it is much easier, as in the header files required and such. For now I always run hsimple.C first and the write the code for graphs line by line which is quite tedious. ROOT Version: V6.18.04 Platform: Windows Hi, you can run C++ code with ROOT with root -q functionname.cpp (ROOT will execute the function called functionname in file functionname.cpp ). You can also open a ROOT prompt with root, and then load the contents of a program with,L myprogram.cpp, at which point you can just call any function that was defined in that file as normal. For more complex usecases, my personal recommendation would actually be to use ROOT as any other C++ library and compile your programs with g++ -o program program.cpp $(root-config -libs -cflags) (you can check what root-config -libs -cflags does by running it in your prompt: it’s just a handy utility to provide all the compilation flags needed to compile a program that depends on ROOT). Cheers, Enrico 1 Like Search for “macro” in: eguiraud: You can also open a ROOT prompt with root, and then load the contents of a program with,L myprogram.cpp, at which point you can just call any function that was defined in that file as normal.

    • I tried doing this but it doesnt work, only shows errors for some reason. error: unknown type name ‘cout’
    • error: expected unqualified-id
    • This was my program:

    #include #include void main()

  2. It;s simple enough and I used a C++ compiler to ensur there were no mistakes so I dont know.

Uhm, that shouldn’t be valid C++ you need either using namespace std; or std::cout and std::endl; How exactly should the code be written then?

  • #include using namespace std;
  • int main() is what i wrote and saved it as hello.cpp it still wont work error: cannot find function ‘hello()’; falling back to,L is what i see See e.g. for the original version and its compilation errors, and for the fixed version. Regarding the second post, as I if you run cpp file through root, the filename should be the same as the function you want root to execute (see that post for more details, or the primer that Wile E. linked. Hope this helps! Enrico Thanks! I am now able to execute files that way but I cannot seem to work the Slits example given in The input is taken but the graph is blank white box and nothing else. I am confused as to why I really can’t say without a reproducer, but my best guess would be or, : How to run c/c++ files on root

How run C file in terminal or code?

Start Coding in the Visual Studio Code Editor – 1. Here we created a C Program folder to store all program code. We can create a folder with any name in any directory.2. Go to the VS Code and click on the Add Folder,3. As we click on the Add Folder, it shows a popup dialog box to select the folder to store the program.4.

After selecting the folder, click on the Add The selected folder appears in the explorer section, as we have shown below.5. Move the mouse over the C PROGRAM folder; it shows a + Click on the button and write the file name as JavaTpoint.c, as shown below. Now write and understand simple C programming in the VS Code editor.

JavaTpoint.c #include // define the header file void main() // define the main function After writing the code, right-click on the program, as shown below. Click on the Run Code option or press Ctrl + Alt + N from the button. It shows the following output.

  • Welcome to JavaTpoint
  • Let’s write a program to calculate the area and perimeter of the rectangle in the VS Code editor.
  • Rectangle.c

#include // header files #include void main() We can click on the Run button or press the Ctrl + Alt + N from the keyboard. It displays the below output. Let’s write another C program to take an input from the user in the Visual Studio Code Editor. Rectangle2.c #include int main() When we click on the Run button or press the Ctrl + Alt + N, it displays the below output.

In the above program, we take length and breadth as input from the keyboard. As the program is compiled, it produces the below statement. Here Output tab is read-only, and hence we cannot take any input from the user. So, we need to add some steps in the code editor to take user inputs from the console/user.

Following are the steps to take input from the user.

  1. First of all, we need to stop the background running the c program by pressing the Alt + Ctrl + M from the keyboard.
  2. After stopping the C file, go & click the File button at the top left corner of the Visual Studio Code Editor, and select the Settings via Preferences, as shown below image.
  3. After clicking the Settings, it shows the image below. In this image, select the extension button to set the settings for the C Compiler.
  4. Click on the Extension button and scroll the drop-down box to select the Run Code Configuration,
  5. Now scroll the right-side pane and Tick on the Run In Terminal.
  6. Go to the c and again execute the program by clicking on the Run, it produces the following results, as shown below.

Can you compile C with gcc?

In order to explain all the steps of compilation, we need to clarify a few programming concepts beforehand. In this article, we will cover what the C language is, how to compile it with a tool like gcc, and what happens when we compile it. All the softwares, programs, websites and apps are written in a certain programming language.

  • Basically, everything we see on the screen of our computers or smartphones are just a lot of code written in different languages and assembled together in a certain way.
  • Every programming language has a different use, and today we are going to focus on C.
  • C is a programming language invented by Dennis Ritchie that first appeared in 1972.

It’s what we call a low-level language, meaning there is only little abstraction between C and machine language, so it can be considered to be closer to the computer’s hardware. C is also a compiled language, as opposed to interpreted, meaning the source files written in C should be compiled in order for them to be executable.

  • Before anything else, let’s talk about the tools we’ll be using in our example.
  • We will be working on a Unix-like operating system, so the examples may vary from Windows.
  • We need to have access to the shell, which is “a program that takes commands from the keyboard and gives them to the operating system to perform” according to http://linuxcommand.org,

For this, we need a terminal, or terminal emulator, which is just a window that lets us interact with the shell. Inside the terminal, we should see the shell prompt, that contains your user name and the name of the machine, followed by the PS1 environment variable that is often the character “$”. Compilation is the translation of source code (the code we write) into object code (sequence of statements in machine language) by a compiler. The compilation process has four different steps:

The preprocessingThe compilingThe assemblingThe linking

The compiler we will be using as an example is gcc which stands for GNU Compiler Collection, The GNU project is an free-software and mass-collaboration project launched by Richard Stallman in 1983, allowing developers to have access to powerful tools for free.

  1. Gcc supports various programming languages, including C, is completely free and is the go-to compiler for most Unix-like operating systems.
  2. In order to use it, we should make sur we install it on our computer, if it’s not already there.
  3. For our example, let’s take a look at a source code inside a file called “main.c”, where “.c” is a file extension that usually means the file is written in C.

This picture is inside the text editor vi: main.c In pink is the preprocessor directive #include that tells the compiler to include the stdio.h header file, but we will come back to it later. In blue are comments about the code, these are useful for remembering what your code actually does months after having creating it.

  • We don’t really need them in such a small program, but it’s good practice to put them.
  • Next we have our entry point, the main() function.
  • It means the program will start by executing the statements that are inside this function’s block, that is between the curly brackets.
  • Here, there are only two statements: one that will print the sentence “Hello, World” on the terminal, and another one that tells the program to “return” 0 if it exited, or ended, correctly.

So once we compiled it, if we run this program we will only see the phrase “Hello, World” appearing. In order for our main.c code to be executable, we need to enter the command “gcc main.c”, and the compiling process will go through all of the four steps it contains.

Is C :\ a root directory?

The root folder, also called the root directory or sometimes just the root, of any partition or folder is the “highest” directory in the hierarchy. You can also think of it in general as the start or beginning of a particular folder structure. The root directory contains all other folders in the drive or folder, and can, of course, also contain files.

  1. You can visualize this with an upside-down tree where the roots (the root folder) are at the top and the branches (subfolders) fall below; the root is what holds together all of its lower items.
  2. For example, the root directory of the main partition on your computer is probably C:\.
  3. The root folder of your DVD or CD drive might be D:\.

The root of the Windows Registry is where hives like HKEY_CLASSES_ROOT are stored. Lifewire ROOT is also an acronym for ROOT’s Object Oriented Technologies, but it has nothing to do with root folders.

What should I install to run C?

How to Install C? – C is a high-level general-purpose language developed by American computer scientist Dennis M. Ritchie between 1969 and 1973 at Bell Labs of AT&T (American Telephone & Telegraph) located in the U.S.A. It was invented for writing UNIX operating system.

It is written in assembly language, Dennis Ritchie and Brian Kernighan published the first edition K & R C or “The C Programming Language” in 1978. Linux OS, Perl, Matz’s Ruby, NumPy, Java’s first compiler, web servers like Apache, Nginx and RDBMS MySQL are all written in C. It is the successor of three structured languages i.e.

BCPL (Basic Combined Programming Language), ALGOL (Algorithmic Language) and B. Many features of C were inherited from these languages while many new features were also introduced such as pointers, struct, data types etc. In 1983 American National Standards Institute (ANSI) set up a committee to standardize the language as it was being used in projects concerning commercial and government projects.

It is a structure oriented programming language. It allows direct access to memory and direct control over the low-level aspects of the computer. It is mainly used for system development work such as designing databases, operating systems, language interpreters, language compilers, assemblers, text editors and much more.

Run C Program in Command Prompt

Many legacy programs are also written in C. It is simple, efficient and easy to learn. It is the base to learn many other programming languages so it is sometimes also referred to as Mother of all programming languages, One major advantage is that it can be compiled on various platforms and produces efficient programs.

It is portable or machine independent also i.e. program once written in C language can be executed on other machines also. It is robust in nature and there are many built-in functions present, which help programmers to develop programs easily and efficiently. We can create our own functions also and can add them to the C library.

It has a modular structure which works as a catalyst for code debugging, code testing and maintenance of code. It also has the ability to extend itself as it can adopt new features easily and effectively. Its versatility makes its efficient choice for high data manipulation software such as 3D animation,

  • It is a case sensitive language i.e.
  • Continue and CONTINUE is treated differently.
  • C follows rules and regulations strictly hence is a strongly tight syntax based programming language.
  • It also provides the functionality of pointers by which the user can directly refer or interact with the memory.
  • We can use recursion i.e.

calling the function in its definition itself hence enables the use of backtracking. It is a procedural language i.e. instructions are carried out step by step. It is also a statically typed language (Statically typed languages are those in which the type of variable is checked during compile time, not at run time.

  1. They are faster in comparison to dynamically typed language) hence errors are detected during a software development cycle.
  2. It has a total of 32 Keywords and 45 operators so it is easy to memorize and simple to learn.
  3. It follows a top-down programming approach.
  4. There are 5 built-in data types i.e.
  5. Integer (int), float, character (char), double and void.

C programs are difficult to debug and understand (unless comments are properly written). C provides no data protection and C compilers can only detect errors, they cannot handle exceptions. There are many versions of C, the latest one is C11, introduced in 2011, supported by all standard C language compilers.

  1. You can install C compiler which converts the C language program into machine language on your systems to run any C program because without compilation no program written in C can be executed.
  2. There are many compilers for C like Turbo C, GCC, Microsoft Visual Studio Express, Xcode, Pelles C and many more.

Many IDEs are also there to work on C such as NetBeans, DevC++, Eclipse, Code:: Blocks, MinGW and many more. Now let us see the installation process of Turbo C++ on Windows.
