Accessing Console From C++

I'm having trouble finding out how to access commands in the console from a c++ program. Specifically, i want to use dd to overwrite a file by using /dev/urandom.

Use the library call "system", as in:

status = system("cp foo bar");

Be careful with special characters to the shell, e.g. quotes, >, <, &, etc, as the command is interpreted by a shell.

Hey thanks a lot. That worked perfectly
