                       Conditional statements are used in a program to instruct the computer to make a decision.

                       A loop allows a set of instructions or a block of code to be executed repeatedly.
                       When a loop repeats forever (endlessly), it is called an infinite loop.

                       Counting loop repeat a block of code a specific number of times.
                       Conditional loops repeat until a certain condition is reached, which means they keep going until
                      the condition remains true.
