Problem Statement:

Create a program that will ask the user to input a number between $0$ and $20.$ Use a do loop to

validate the user's input so if the user inputs a number outside of the $0-20$ range, the program will ask

the user to input another number. Once the user has input a valid number, the program will generate a

table of squares for all whole numbers up to the number the user input. Table should be formatted as

seen in the output below.

Output:

Enter the number of entries for the table.

Please enter a whole number between $0$ and $20$: $10$

The table of squares for $10$ values
