Question

Assume that the int variables i and j have been declared, and that n has been declared and initialized.

Answer 1

Answer:

public class num6 {

   public static void main(String[] args) {

       int n = 4;

       for(int i = 1; i <= n; ++i) {

           for(int j = 1; j <= i; ++j) {

               System.out.print("* ");

           }

           System.out.println();

       }

   }

}

Explanation:

This solution is implemented in Java

Two for loops are required for this (an inner nd outer for loop).

The innner and outer for loops can be seen as implementing rows and columns (so on the first 'row' i=1, so a single star is printed, on the second row, i =2, two stars are printed and so on, all on seperate lines)
