random(max);

max- the upper limit of the random number to retrieve.

int r = random(10);
// r is >= 0 and < 10
// The smallest value returned is 0
// The largest value returned is 9
NB: When max is 0, the result is always 0.
random(min,max);
Parameters:
min- the lower limit (inclusive) of the random number to retrieve.max- the upper limit (exclusive) of the random number to retrieve.
Returns: a random value from min and up to, but not including max.
int r = random(10, 100);
// r is >= 10 and < 100
// The smallest value returned is 10
// The largest value returned is 99
NB: If min is greater or equal to max, the result is always 0.
