childprocess.c

/*

In this example, the fork() function creates a new process, and the execl() function executes the another_program program in the child process. The wait() function is used to wait for the child process to finish.

Remember to replace another_program.c and another_program with the actual names of the program you want to run.

Now, go forth and ninja-ly execute those C programs!
