[norman]

Is it possible to run another program say program2 from a program say program1 in C? If so can someone suggest me a best and easy way for achieving this?

[joel]

I have a C program and I wanted to invoke or execute another C program from the first C program. Is there any option in C language for doing this? What is the command used for this?

If the C program is run in a UNIX operating system then you can use the exec, execl, execv,execle, execve, execlp, execvp functions to invoke another program from within a C program.
