The AP Exam uses the following relational (comparison) operators: =, ≠, >, <, ≥, and ≤.
As well, AND, OR and NOT are used instead of and, or and not.

A comparison using a relational operator evaluates to a Boolean value. For example, a = b evaluates to true if a and b are equal; otherwise, it evaluates to false.

We want to print the phrase "Another day, another victory for the OG" exactly 19 times. What kind of control structure should we use?

• If Statement

• While Loop

• Break Statement

• For Loop

The following code continually asks the user for a password until they guess the correct password, then ends. But there is one problem.

• Change the True in line 3 to be password != SECRET_PASSWORD so that the program doesn't loop infinitely.

• Change the True in line 3 to be password == SECRET_PASSWORD so that program doesn't loop infinitely.

• Add a break; statement after line 6 so that the program doesn't loop infinitely.

• Put line 7 inside of an else statement.

We want to simulate constantly rolling a dice until we get an even number. What kind of loop should we use?

• For loop

• While Loop
