13. Using For Loop

#include <stdio.h>
 int main()
 {
     int i,j;
     for(i=2;i<=10;i=i+2)
     {
         for(j=1;j<=5;j++)
         {
             printf("%d ",i);
         }
         printf("\n");
     }
 return 0;
 }

14. Using While Loop

 /* using while loop */

 #include <stdio.h>
 int main()
 {
     int i=1,j;
     while(i<=5)
     {
         j=1;
         while(j<=5)
         {
             printf("%d ",i*2);
             j++;
         }
         printf("\n");
         i++;
     }
     return 0;
 }

Get the following Output:

5 5 5 5 5
7 7 7 7 7
9 9 9 9 9

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

             j++;
         }
         printf("\n");
         i++;
     }
     return 0;
 }
