What is printed after the code segment has been executed?

• Nothing will be printed

• yes

• no

• yesno

Answer explanation

y/x is integer division so 3/5 will equal zero, making the if false.  The code will then execute the statement after the if, printing "no".

A school assigns letter grades based on the following scale:  90 or above is an A, 80 to 89 is a B, 70 to 79 is a C, 65 to 69 is a D, and below 65 is an F.  The following code was written to assign letter grades where score holds the numerical value and grade holds the associated String letter grade.

Consider the following code segment.

What would print after the code segment has been executed if the value of  score is 93? 

• B

• A

• D

• F

• C

Answer explanation

Each of the if statements, except the last one, is true, meaning that grade will be reassigned for each of those if blocks.  The last grade assignment was "D", so that is what will be printed.
