Someone help me

Answer 1

The program is an illustration of loops.

Loops are used to perform repetitive and iterative operations.

The program in C++ where comments are used to explain each line is as follows:

#include <iostream>

using namespace std;

int main(){

   //This declares and initializes all variables

   string star = "*", blank = " ", temp;

   //The following iteration is repeated 8 times

   for (int i = 1; i <= 8; i++) {

       //The following iteration is repeated 8 times

       for (int j = 1; j <= 8; j++) {

           //This prints stars

           if (j % 2 != 0) {

               cout << star;

           }

           //This prints blanks

           else if (j % 2 == 0) {

               cout << blank;

           }

       }

       //This swaps the stars and the blanks

       temp = star;

       star = blank;

       blank = temp;

       //This prints a new line

       cout << endl;

   }

}
