If you exchange 372 pennies for dollar bills, how many bills do you get? How many pennies are left over?

Answer:

Number of dollar bills is 372 / 100 == 3
Left over pennies is 372 % 100 == 72

Practice with Remainder Operator

For positive integers, INT % X means to fit as many X as you can into INT, and then the left over amount is the value of the expression. Try that with the following:

Expression	Result	Expression	Result
7 3		7 5
10 5		10 6
129 100		1999 100
17 2		18 2

QUESTION 16:

If X is odd, what is X % 2?
