Use this statement at the very beginning of your main() function:

srand((unsigned)time(0));

In order to limit your values, use the modulus operator (%) with the range of values you wanted. Suppose you wanted a value between 0 and 50 (including 0, but not 50). Use the statement:

int x = rand() % 50;

If you want to have a higher minimum value (such as 50 to 100 including 50 but not 100), use

int x = rand() % 50 + 50; // Generates random number between 0 and 50, then adds 50 to it
