19. 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);
         }
         printf("\n");
     }
 return 0;
 }

20. Using While Loop

 /* using while loop */

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

     int i=1,j;
     while(i<=5)
     {
         j=1;
         while(j<=i)
         {
             printf("%d ",j*2);
             j++;
         }
         printf("\n");
         i++;
     }
     return 0;
 }
