Source Code:

1. Using For Loop

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

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

Get the following Output:

2 4 6 8 10
2 4 6 8 10
2 4 6 8 10
2 4 6 8 10
2 4 6 8 10

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

4. Using while Loop

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

Get the following Output:

1 3 5 7 9
1 3 5 7 9
1 3 5 7 9
1 3 5 7 9
1 3 5 7 9

#include<stdio.h> 
 int main()
 {
     int i,j;
     for(i=1;i<=5;i++)
     {
         for(j=1;j<=9;j=j+2)
         {
             printf("%d ",j);
         }
         printf("\n");
     }
     return 0;
 }

6. 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 ",j*2-1);
             j++;
         }
         printf("\n");
         i++;
     }
     return 0;
