How to execute c program in command line

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. 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.

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.

You need a developer command prompt window, which is a regular command prompt window that has all the required environment variables set. Your first walkthrough task is to find the right shortcut to use. A developer command prompt shortcut automatically sets the correct paths for the compiler and tools, and for any required headers and libraries.

Some of these values are different for each build configuration. You must set these environment values yourself if you don't use one of the shortcuts. Because the build environment is complex, we strongly recommend you use a developer command prompt shortcut instead of building your own.

These instructions vary depending on which version of Visual Studio you are using. To see the documentation for your preferred version of Visual Studio, use the Version selector control. It's found at the top of the table of contents on this page. If you've installed Visual Studio on Windows 10 or later, open the Start menu, and choose All apps. Then, scroll down and open the Visual Studio folder not the Visual Studio app. 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. In the command prompt window, enter cl and verify that the output looks something like this:.

You must fix this issue before you can continue. Or, reinstall the Build Tools from the Visual Studio downloads page. Type the compilation command in following syntax —. This is the final step where you run the newly created executable file. These are the steps you need to follow in order to compile and run a C program using command prompt cmd.

I hope it is very much clear now. If you face any issues, do let us know in the comment section. Your email address will not be published.

Prerequisites before compiling and running any C program using command prompt : To run your C program using cmd, here are the prerequisites for Windows.

Prerequisite 1: Download and Install a compiler To compile any program, you need to have a suitable compiler installed on your development environment. As an example, we will use gcc compiler to compile C program. Prerequisite 2: C program with required file extension You must save your C program with.

Below is the sample C program that we will execute using command prompt. Step 1: Open command prompt Go to Windows search and type cmd.

Sounds like a trivial use-case for the system function: system "asterisk -rx reload" ; If you need very fine-grained control of the child process there are better ways, but this is simple to get going.

Improve this answer. AngelDream: The program that calls the system function must have the correct privileges to execute the asterisk program.

For example, if your program is running as a normal user, but asterisk requires a root user, then the system call will not work because the your program is not allowed to execute asterisk. Community Bot 1 1 1 silver badge. Alex Reynolds Alex Reynolds Sign up or log in Sign up using Google.
