Question Four

Write a program that asks the user to enter a number between 1 and 10 then prints the related multiplication table. The program must ask the user if he wants to continue by choosing another number or quit.

NB: you have to run your program then join a screenshot of the execution to your answer file

Typical run of the program:

Give your proposed number between 1 and 10: 4

The Multiplication Table of 4 is

1 * 4 = 4

2 * 4 = 8

3 * 4 = 12

4 * 4 = 16

5 * 4 = 20

6 * 4 = 24

7 * 4 = 28

8 * 4 = 32

9 * 4 = 36

10 * 4 = 40

Do you want to continue Y/N? Y

Give your proposed number between 1 and 10: 7

The Multiplication Table of 7 is

1 * 7 = 7

2 * 7 = 14

…
