Question

Write a program that takes input from a user for number of rows and number of columns and prints out a block of characters that is based on these 2 parameters. The program should keep asking the user for input, and printing out the result, until the user enters zero for each of the input parameters. A session should look exactly like the following example (including whitespace and formatting - although note that there is no whitespace at the end of each of these lines), with all manners of different numbers for inputs and the output $./block Enter number of rows and columns 10 10 X. X.X.X.X.X.X.X.X.X. X.X.X.X.X.X.X.X.X.X. X.X.X.X.X.X.X.X.X.X. X.X.X.X.X.X.X.X.X.X. X. X.X.X.X.X.X.X.X.X X.X.X.X.X.X.X.X.X.X. X.X.X.X.X.X.X.X.X.X X.X.X.X.X.X.X.X.X.X. X. X.X.X.X.X.X.X.X.X. X.

//get rows and columns
cin >> rows >> columns;
//loop through each row
for(int i=0;i<rows;i++){
//loop through each column
for(int j=0;j<columns;j++){
//print output
cout << "X.";
