What's the Right Way to use the rand() Function in C++?

Question

I\'m doing a book exercise that says to write a program that generates psuedorandom numbers. I started off simple with.

#include \"std_lib_facilities.h\"

in         


        

Answer 1

Option 2 isn't difficult, here you go:

srand(time(NULL));

you'll need to include stdlib.h for srand() and time.h for time().
