Fiel Wrote:lowerBound = 25
upperBound = 75

rand() % (75 - 25 + 1)
rand() % (51)

So it will generate a number between 0 and 50 - not really what you want.

Yes it is. That expression is added to lowerBound, making the range exactly what it needs to be.

The +1 is needed, if you want to be accurate. Unless upperBound isn't supposed to be inclusive.
