7 times 3 = 21
6 times 3 = 18

Re: Help with for loop

Make a for loop that starts from 12 to 1 (Decrementing here )
and then multiply 3 by the index and cout the result.

               answer=3*i;
               cout<<index<<" times 3 = "<<answer<<endl;
          }

-iostream.h should be iostream
-it's int main
-you're mixing index with the variable i

etc etc and use [code][/code] tags next time.

Re: Help with for loop

Keep it simple:

C++ Syntax (Toggle Plain Text)
for (int i = 12; i; i--)
  cout << i << " times 3 = " << 3*i << '\n';
for (int i = 12; i; i--)
  cout << i << " times 3 = " << 3*i << '\n';
