#include<stdio.h>
int main()
{
    int i, j, result;
    printf("\n");
    for (i = 1; i < 10; i++)
    {
        for (j = 1; j <= i; j++)
        {
            result = i * j;
            printf("%d*%d=%-3d", i, j, result); /* -3d means left-aligned, occupying 3 spaces */
        }
        printf("\n"); /* newline after each row */
    }
}

The above example outputs:

1*1=1  
2*1=2  2*2=4  
3*1=3  3*2=6  3*3=9  
4*1=4  4*2=8  4*3=12 4*4=16 
5*1=5  5*2=10 5*3=15 5*4=20 5*5=25 
6*1=6  6*2=12 6*3=18 6*4=24 6*5=30 6*6=36 
7*1=7  7*2=14 7*3=21 7*4=28 7*5=35 7*6=42 7*7=49 
8*1=8  8*2=16 8*3=24 8*4=32 8*5=40 8*6=48 8*7=56 8*8=64 
9*1=9  9*2=18 9*3=27 9*4=36 9*5=45 9*6=54 9*7=63 9*8=72 9*9=81
