The standard way of generating 'random' numbers in C is the rand() function. This function returns any random number so to get it within a certain range take the modulus of it. i.e.

rand()%10 returns numbers between 0-9, inclusive

I quoted 'random' above because the numbers aren't truly random, in fact you'll get the same string of numbers for any given seed. You seed the generator by calling srand( seed ). A popular technique is to seed with the current time, so you'll get a new sequence everytime you run the program (at a different time of course).

srand( time(0) );

Random number generation is actually a very complicated task. The inbuilt C functions (rand(), srand(), etc) are notorious for generating poor random numbers. The book "Numerical Recipes in C" has lots on information on generating "good" random numbers with source code. Check out chapter 7 at:
