25. Using For Loop

#include <stdio.h>
 int main()
 {
     int i,j;
     for(i=1;i<=5;i=i+1)
     {
         for(j=1;j<=i;j++)
         {
             printf("%d ",j*5);
         }
         printf("\n");
     }
 return 0;
 }

     while(i<=5)
     {
         j=1;
         while(j<=i)
         {
             printf("%d ",j*5);
             j++;
         }
         printf("\n");
         i++;
