Question

**array must have header for each dimension when outputted**

**Can not use "printf"**

**Must use string**

**Must ask user if program should be run again**

**must clear screen if run again**

Write a C++ program that will use a two-dimensional array to create and store the multiplication tables for the integers 1-10. The table shall be created in a function name “multiply_me” and outputted in the main function. You must use global variables to transfer information to and/or from the table. Your output shall be neatly displayed on the console.
