And i thought that "if statement" needs to be paired with an "else"?

  int i;
  for (i=1; i<=10; i++)
  {
    cout.width(8);
    cout <<  i;

    cout << i*i << endl;

Why can't you just add another variable/calculation to the output stream, something like:

cout << integer << ' ' << integer*5 << endl;

int a=5;
if ( a > 10 )
{
  a = a-10;
}
else
{
  a = a + 1;
}
a = a + 2;

int a=5;
if ( a > 10 )
{
  a = a-10;
}
a = a + 2;
