Compile and Execute C Program

Compile and Execute C Program

Let us see how to save the source code in a file, and how to compile and run it.

Following are the simple steps:

1. Open a text editor and add the above-mentioned code.

2. Save the file as hello.c

3. Open a command prompt and go to the directory where you have saved
the file.

4. Type gcc hello.c and press enter to compile your code.

5. If there are no errors in your code, the command prompt will take you to
the next line and would generate a.out executable file.

6. Now, type a.out to execute your program.

7. You will see the output "Hello World" printed on the screen.

$ gcc hello.c $ ./a.out Hello, World!

Make sure the gcc compiler is in your path and that you are running it in the
directory containing the source file hello.c.
