Well I've seen people get a random number like this:

int random_number1to100 = ( rand()%100 ) + 1;

But I've also heard that that isn't so good because on some random number
generators, the low order bits aren't that random.  You could also do:

double random_number0to1 = double( rand()/MAX_RANDOM );

That should give you a float from 0 to 1 which you can use your BASIC
methods on to convert to any range of numbers.  I think the maximum value
a random number can take (MAX_RANDOM here) is the same as MAX_INT.
Anybody??  If you want to avoid floating point math you could try:

int random_number1to100 = 100 * rand() / MAX_RANDOM + 1;

but that might cause overflow.  And you can't solve that by making it
rand() / MAX_RANDOM * 100 + 1 because that will always give you 1.
