Theres two ways you can do this:

Run the program from within the C program, using something like this: How to execute a command and get output of command within C++ using POSIX? The answer is written for C++ but it's all the same calls as in C.
Pipe the output of the other program into your C program. This means your C program won't be executed before the other program though. For example, the command:

ls | myprog

will take the output of "ls" and feed it into myprog, which can read it via scanf or fgets, for example.
