run time in c

To run a C program, you need to compile and execute it. Here are the steps to do so:

1. Write your C program in a text editor and save it with a .c extension, for example, "program.c".

2. Open a terminal or command prompt and navigate to the directory where your C program is saved.

3. Compile the C program using a C compiler like GCC (GNU Compiler Collection). The command to compile a C program is: gcc program.c -o program This command will generate an executable file named "program" from your C source code.

4. Once the compilation is successful, you can run the program by executing the generated executable file. The command to run the program is: ./program Replace "program" with the actual name of your executable file.

5. The C program will now run, and you will see the output (if any) in the terminal or command prompt.

That's it! You have successfully compiled and run a C program.

Please note that the above steps assume you have a C compiler installed on your system. If you don't have one, you can install GCC or any other C compiler based on your operating system.
