More Nested Loops

This example displays a simple multiplication table.

#include <iostream.h>
#include <iomanip.h>

void main(void)
{
  cout << "      1   2   3   4   5" << endl;
  cout << "-----------------------" << endl;
  for (int i = 1; i <= 5; i++)
  {
    cout << i << " |";
    for (int j = 1; j <= 5; j++)
      cout << setw(4) << i * j;

    cout << endl;
  }
}


Output:

      1   2   3   4   5
-----------------------
1 |   1   2   3   4   5
2 |   2   4   6   8  10
3 |   3   6   9  12  15
4 |   4   8  12  16  20
5 |   5  10  15  20  25
