4.4) Example of Making Decisions

When the program reaches line 6, it tests what is inside the round brackets to see if it is true. If the test is true (i.e. a > b) then it goes inside the if statement and performs the printing to the screen. If the test is false (i.e. b > a) then the print statement is ignored and the code jumps to line 8 and then continues in the program.
