this is in C++

Would I need to use a while loop to write this program? Cause I just learned about it, but I'm not sure if it would require it. I thought I'd ask. Any help would go a long way! Thank you so very much:

2. Multiplication Table Write a program that reads in the size of a multiplication table and then prints out the table. Your program should work for tables of all sizes between 1 and 15 . When the user enters the table size, make sure it is a number from 1 to 15 . If it is not a valid size, ask the user to re-enter the number. Allow the user to construct as many multiplication tables as they would like before ending the program. Enter the table size: 25 Size must be between 1 and 20, Enter the table size: 5 Would you like to print another table (Y or N): Y Enter the table size: 1 111
