Thread: help making triangle

so I am trying to make a triangle in which :

1. The number of elements in a row is equal to the row number
2. Each element is the product of the row number by the column number.

Example Output:
Enter a number: 7
1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
7 14 21 28 35 42 49

However when I run the program all I get is:
Enter a number: 7
1
2 2
3 3 3
4 4 4 4
5 5 5 5 5
6 6 6 6 6 6
7 7 7 7 7 7 7


PLEASE HELP!!! Thanks in advance

Heres my code as of now:

Code:

#include <stdio.h>

int main ()
{
        int num, row, col;

        printf("Enter a number: ");
        scanf("%d", &num);

        for (col = 1; col <= num; col++) {
                for (row = 1; row <= col; row++) {
                        col = col*row;
                        printf("%5d", col);
                }                
                printf("\n");
        }
}

I'd change the order of the for loops: row first, then col. The value needed changes with every col, not just with every row.

thanks, that really did the work.
