Aug 10, 2017 · Creating and compiling a C program using an IDE is like waving some magic wand. However, a beginner must know how to compile and run C programs using command line in Windows based operating system. To create a C program using command line you need two basic software’s.

Feb 7, 2024 · In C, we can provide arguments to a program while running it from the command line interface. These arguments are called command-line arguments. In this article, we will learn how to write a command line program in C.
Jul 30, 2024 · In this article, we’ll explore how to compile and run a C program from the Windows command prompt using the MinGW system environment, an easy-to-install version of the GCC compiler to execute correctly.
Jul 30, 2024 · Step 1: Setting Up Your Environment. Before proceeding to write the first program, the user needs to set up a C program compiler, which would compile and execute the first program. Here we have used a Windows-based GCC compiler to compile and run the program.

The Visual Studio build tools include a C compiler that you can use to create everything from basic console programs to full Windows Desktop applications, mobile apps, and more. Microsoft C/C++ (MSVC) is a C and C++ compiler that, in its latest versions, conforms to some of the latest C language standards, including C11 and C17.
This walkthrough shows how to create a basic, "Hello, World"-style C program by using a text editor, and then compile it on the command line. If you'd rather work in C++ on the command line, see Walkthrough: Compiling a Native C++ Program on the Command Line. If you'd like to try the Visual Studio IDE instead of using the command line, see Walkthrough: Working with Projects and Solutions (C++) or Using the Visual Studio IDE for C++ Desktop Development.
To complete this walkthrough, you must have installed either Visual Studio or the Build Tools for Visual Studio and the optional Desktop development with C++ workload.
Visual Studio is a powerful integrated development environment that supports a full-featured editor, resource managers, debuggers, and compilers for many languages and platforms. For information on these features and how to download and install Visual Studio, including the free Visual Studio Community edition, see Install Visual Studio.
The Build Tools for Visual Studio version of Visual Studio installs only the command-line toolset, the compilers, tools, and libraries you need to build C and C++ programs. It's perfect for build labs or classroom exercises and installs relatively quickly. To install only the command-line toolset, download Build Tools for Visual Studio from the Visual Studio downloads page and run the installer. In the Visual Studio installer, select the Desktop development with C++ workload (in older versions of Visual Studio, select the C++ build tools workload), and choose Install.
When you've installed the tools, there's another tool you'll use to build a C or C++ program on the command line. MSVC has complex requirements for the command-line environment to find the tools, headers, and libraries it uses. You can't use MSVC in a plain command prompt window without some preparation. You need a developer command prompt window, which is a regular command prompt window that has all the required environment variables set. Fortunately, Visual Studio installs shortcuts for you to launch developer command prompts that have the environment set up for command line builds. Unfortunately, the names of the developer command prompt shortcuts and where they're located are different in almost every version of Visual Studio and on different versions of Windows. Your first walkthrough task is to find the right shortcut to use.
If you've installed Visual Studio 2022 on Windows 10 or later, open the Start menu, and choose All apps. Then, scroll down and open the Visual Studio 2022 folder (not the Visual Studio 2022 app). Choose Developer Command Prompt for VS 2022 to open the command prompt window.
If you've installed Visual Studio 2019 on Windows 10 or later, open the Start menu, and choose All apps. Then, scroll down and open the Visual Studio 2019 folder (not the Visual Studio 2019 app). Choose Developer Command Prompt for VS 2019 to open the command prompt window.
If you've installed Visual Studio 2017 on Windows 10 or later, open the Start menu, and choose All apps. Then, scroll down and open the Visual Studio 2017 folder (not the Visual Studio 2017 app). Choose Developer Command Prompt for VS 2017 to open the command prompt window.
If you've installed Microsoft Visual C++ Build Tools 2015 on Windows 10 or later, open the Start menu, and choose All apps. Then, scroll down and open the Visual C++ Build Tools folder. Choose Visual C++ 2015 x86 Native Tools Command Prompt to open the command prompt window.
If you're using a different version of Windows, look in your Start menu or Start page for a Visual Studio tools folder that contains a developer command prompt shortcut. You can also use the Windows search function to search for "developer command prompt" and choose one that matches your installed version of Visual Studio. Use the shortcut to open the command prompt window.
Next, verify that the developer command prompt is set up correctly. In the command prompt window, enter cl (or CL, case doesn't matter for the compiler name, but it does matter for compiler options). The output should look something like this:
There may be differences in the current directory or version numbers, depending on the version of Visual Studio and any updates installed. If the above output is similar to what you see, then you're ready to build C or C++ programs at the command line.
1.In the developer command prompt window, enter cd c:\ to change the current working directory to the root of your C: drive. Next, enter md c:\hello to create a directory, and then enter cd c:\hello to change to that directory. This directory will hold your source file and the compiled program.
2.Enter notepad hello.c at the developer command prompt. In the Notepad alert dialog that pops up, choose Yes to create a new hello.c file in your working directory.
3.In Notepad, enter the following lines of code:
4.On the Notepad menu bar, choose File > Save to save hello.c in your working directory.
5.Switch back to the developer command prompt window. Enter dir at the command prompt to list the contents of the c:\hello directory. You should see the source file hello.c in the directory listing, which looks something like:
The dates and other details will differ on your computer. If you don't see your source code file, hello.c, make sure you've changed to the c:\hello directory you created, and in Notepad, make sure that you saved your source file in this directory. Also make sure that you saved the source code with a .c file name extension, not a .txt extension.
This "Hello, World" example is about as basic as a C program can get. Real world programs have header files and more source files, link in libraries, and do useful work.
You can use the steps in this walkthrough to build your own C code instead of typing the sample code shown. You can also build many C code sample programs that you find elsewhere. To compile a program that has more source code files, enter them all on the command line:
cl file1.c file2.c file3.c
The compiler outputs a program called file1.exe. To change the name to program1.exe, add an /out linker option:
cl file1.c file2.c file3.c /link /out:program1.exe
And to catch more programming mistakes automatically, we recommend you compile by using either the /W3 or /W4 warning level option:

Mar 13, 2024 · Are you ready to turn your C code into an executable program? The GNU C compiler, also known as GCC, is a simple Linux-based C compiler that's easy to use from the command line. If you're using Linux, including Ubuntu, Fedora, and Linux Mint, you can install GCC from your distribution's package manager.
