Quick Answer. Q represents rational numbers because all rational numbers are a quotient. This means that each rational number can be expressed by a fraction with a denominator other than zero and a numerator that is a whole number. Whole numbers, fractions and decimals are all rational numbers.
rand() % 100 gives you a (almost) random number between 0 and 99*. (rand() % 100) + 50 shifts the range by 50, so it gives you a random number between (0+50) and (99+50), so 50 to 149. To get a range of 50 to 100, you need to make sure that the upper limit after shifting the range is 100, so: (rand() % 51) + 50 gives a range of (0+50) to (50+50), so 50 to 100.
