Today I’m going to show you how to compile and run a C program in command prompt. This process is very simple but it does require some basic knowledge of using the command line terminal, so if this doesn’t make sense now, please go back later and come back to it after reading about what we’re doing first.
The “how to run code in command prompt” is a blog post from Tech Support Whale that explains the process of compiling and running a C program in command prompt.
This article explains how to build and execute a C program on Windows command prompt in four easy steps. Before you proceed with the stages, you must first fulfill the two criteria listed below in order to ensure that these four processes go well.
Let’s get started. By the conclusion of this tutorial, you should be able to successfully run your C program from the command line without any errors.
Before compiling and executing any C program from the command line, the following prerequisites must be met:
Here are the Windows requirements for running your C program using cmd.
1st Prerequisite: Get a compiler and install it.
A proper compiler must be installed on your development environment in order to build any software. Different compilers are available on the market for various programming languages. The compiler you choose should be depending on the programming language you’re using. Some of them are free to use, while others are not.
We’ll use the gcc compiler to build a C program as an example.

Prerequisite 2: A C program with the appropriate file extension is needed.
You must save your C program with the.c extension using any text editor or integrated development environment (IDE). If you use an IDE, it will assist you in quickly resolving compilation difficulties while also increasing your coding productivity.
The example C program that we will run using the command prompt is shown below.
int main #include stdio.h> () return 0; print(“Welcome to TechSupportWhale!”);
To execute a C program at the command prompt, follow these steps:
Here is a step-by-step guide on compiling and running a C program from the command line.
To begin, open a command prompt.
Type cmd into the Windows search box. “Run as administrator” by right-clicking on the command prompt.
It’s worth noting that running the command prompt in Administrative mode isn’t required. With local user permissions, you can launch a command prompt.
Step 2: Verify that the gcc compiler is available.
Check if the gcc compiler is installed on your PC before building your software. Type the command command on the command line to verify the gcc compiler installation details.
gcc –v
If this program produces the following gcc compiler version information, then gcc is installed on your computer and available from the command line.
If you see the message “gcc is not recognized as an internal or external command, operable program, or batch file,” it means “gcc is not recognized as an internal or external command, operable program, or batch file.” If you get an error notice, the first thing you should do is fix it by changing the environment variable.
Here’s a link to a helpful article: gcc isn’t recognized as a command that may be used both within and outside.
Step 3: Make your C application executable.
Navigate to the location of your C program file. Compile the command using the following syntax —
gcc<program file name> -o -o -o -o -o -o -o -o -o -o -o -o -o
Press the enter key after typing the following command.
welcome executable gccWelcome Message.c
The welcome executable executable file is created by the compiler.
Note that if the –o parameter is omitted, the compiler builds an executable file with the name a.exe.
Step 4: Execute the program
This is the last stage, when you use command prompt to launch the freshly produced executable file (.exe file).
- In a command prompt, go to the directory where the executable is stored and input the name of the executable file without the extension as shown below.
- On the keyboard, press the Enter key.
Last but not least,
That is all there is to it. These are the steps you must take to build and execute a C program from the command line (cmd). I hope everything is obvious now. Please let us know if you have any problems in the comments area.
Good luck with your studies.
