can someone tell me how to call a program?
im lost

first you have to know its number....
(sorry, I couldnt resist)

Your question is not very descriptive...
Do you mean from within you program, via a pipe, or just plain 'how do I execute my compiled program'?

Provide more detail and you will get a better answer.

sorry, i meant how do i run a program from within the one i am making
and if you dont mind answering, how do i find the programs number?

i'd bet it'd be on the "programs directory listing".

#include <cstdlib>

...

std::system("yourprogramname.exe");

You use the system function, in cstdlib. It simply executes whatever you want it to.

Why does system() work for me in Dev-Cpp (mingw compiler) when i include iostream?

nindoja · Sep 30th, 2005, 4:36 PM

@snow: because Dev-Cpp automatically includes some header files for you

Most likely it's the wrong path. call it with the directory as well... like...

system("c:\\your\\dir\\to\\exe\\here\\whatever.exe");
