use of exec() or system() in php

[Anon]

I code a simple program in linux.
example:

char * main()
{
return "Hello,World";
}

Now I want to know how
can I load this program in php
using exec() or system() to get the
return value "Hello,World" and show it
in IE.

Please give the detail sample.Thanks in advance.

The documentation may help you:

system() will do for an executable generating text, otherwise use passthru()
