Help with for loop

Jun 1st, 2009

Hi, im new to c++ and wondered if anyone could help me with this

Use a for loop to display 3 times table backwards

12 times 3 = 36
11 times 3 = 33
10 times 3 = 30
9 times 3 = 27
8 times 3 = 24
7 times 3 = 21
6 times 3 = 18
5 times 3 = 15
4 times 3 = 12
3 times 3 = 9
2 times 3 = 6
1 times 3 = 3

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

-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.

Keep it simple:

 Help with Code Tags 
 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';
