How to call a process into the background in Unix on C++ program

hi
As we generally make a procee to run in background by adding an ampersand (&) to the command , the same way we can add an ampersand to the command as a parameter to system ..e.g

#include<stdio.h>

main()
{
   system("ls > output &");
}


this small code will run ls command in background and redirect the output to a file named output
