Running another program and reading it's stdout

S

Stuart Moore

I've tried searching for the following, but I've had no luck.

I want to execute another program from within my C++ program, and read
it's stdout in a similar way to reading from a file. I do not need to be
able to send data to it's stdin.

I'm using g++ on linux, but would prefer a compiler independent option
if one exists.
