Hi, I was wondering how one might go about opening a program, (console program for simplicity) and say there is a menu with different programs you could run, and when a user hits one of those choices, the current program will close or cease running, and the new program will start to run. Im sure this is a fairly simple problem. Any ideas? Im working with the C language. - Thanks.

Operating system?

With linux/unix you can exec*().

With windows there are functions like CreateProcess() I think.

It depends on what O/S you're targetting. If it's windows, you could try looking at the _spawn function.

or just simply: "system("dir");"

Just a note: system() is blocking and doesn't allow your app to continue until after the program that was executed quits. The return value is the exit code of the program.
