C++ program to print a hollow square shape using for loops, if else and asterisks

Brief Explanation of Code:

• Program takes input form user one is height and other is width of square and print respective size of hollow square on console
• There is one main for loop in a program which runs equal to height of square. Other 3 loops runs for width in side main loop
• There is one if , else if and else statement in the program each contain a for
