CONSIDER THE FOLLOWING CODE:
void Question()
{
      int i, j;
      for (i = 1; i <= 4; i++)
      {
            for (j = 1; j <= 4; j++)
            {
                  if (i <= j)
                        cout << " " << j*i;
                  else
                        cout << " " << "*";
            }
            cout << endl;
      }
}

Select one:

a. 1 2 3 4
* * * *
* * * *
* * * *

b. 1 2 3 4
4 6 8 8
9 12 12
16 * * *

c. 1 2 3 4
* 4 6 8
* * 9 12
* * * 16

d. 1 * * 4
* 4 6 8
* * 9 12
* * * 16

please explain how you get the answer. Thank you

Explanation / Answer

void Question()
{
int i, j;
for (i = 1; i <= 4; i++)   //This loop starts from i = 1 to 4.
{
for (j = 1; j <= 4; j++)   //This loop starts from j = 1 to 4.
{
if (i <= j)           //If i <= j, (i.e., for upper triangular values.)
cout << " " << j*i;   //Will print the value(integer) j * i.
else
cout << " " << "*";   //For all other values, will just print a *.
}
cout << endl;   //Move on to next line.
}
}
//Therefore, the output is:
1    2    3    4
*    4    6    8
*    *    9    12
*    *    * 16
