Printing pattern 7

1
1*2
1*2*3
1*2*3*4

i used as outer loop variable for printing no. of lines=4
j used to control printing * and nos. in each line.
In this pattern, we can figure out that star does not get printed when value of i equals value of j.

#include<stdio.h>
int main()
{
         int i,j;

         for(i=1;i<=4;i++)
         {
                 for(j=1;j<=i;j++)
                 {
                           printf("%d",j);

                           if(i!=j)
                                 printf("*");
                 }

                  printf("\n");
            }

            return 0;
}
