Question

You are given a 9*9 grid as shown in the figure below. You can determine the color

of each square from the grid. The number of each square is also shown below. Write a C++ program for

this below given grid. The user is given two options to select from.

Part A: When the user selects 1st option, the user will enter number of square in this grid (any

number from 1-81). Your program will determine the color of the square.

Part B: When the user enters 2nd option, the user will enter two numbers from this grid. Your

program will determine if the two squares entered in this 9*9 grid have same color or not.
