Question

Draw a flowchart to continue receiving numbers and output if they are divisible by 6 or not until a zero is entered. When a zero is entered, the program should output how many of the entered numbers were divisible by 6, then it stops. IMPORTANT RESTRICTION: you are not allowed to divide the number by 6; therefore, you are not allowed to use the remainder operator (%) over 6 to verify through the remainder if the number is divisible by 6. You may use any other math trick you wish.

Answer 1

In the given flowchart, the outer while loop ensures that we continue receiving numbers until a 0 is entered.

To check for the divisibility, instead of using % operator, we've used successive subtraction for positive numbers and addition for negative numbers to check if it is divisible by 6 or not.
