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

A good answer might be:

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

Practice with Remainder Operator

For positive numbers, INT % X means to fit as many X's 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 13:

Say that your program needs to test if a variable val is odd or even:

int x = ...... ;

if ( ___________________ )

  System.out.println( x + " Is even " );
else
  System.out.println( x + " Is odd " );

Fill in the blank so the fragment works.
