Sample C Program On Two Dimensional (2-D) Array.

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>

main()
{

int arr [3] [4];
int i, j;
clrscr();

for(i = 0; i < 3; i++)
  {
     for(j = 0; j < 4; j++)
       {
          printf(" \n Enter the arr[%d] [%d] element: ", i, j);
          scanf(" %d ", &arr[i][j] );
       }
  }

printf(" Array elements are\n ");

for(i = 0; i < 3; i++)
  {
     for(j = 0; j < 4; j++)
         printf(" %d \t ", arr[i][j] );
         printf(" \n ");
  }

getch();
}


OUTPUT:

Enter the arr[0] [0] element: 678

Enter the arr[0] [1] element: 543

Enter the arr[0] [2] element: 234

Enter the arr[0] [3] element: 543

Enter the arr[1] [0] element: 124

Enter the arr[1] [1] element: 432

Enter the arr[1] [2] element: 456

Enter the arr[1] [3] element: 677

Enter the arr[2] [0] element: 321

Enter the arr[2] [1] element: 564

Enter the arr[2] [2] element: 432

Enter the arr[2] [3] element: 654

Array elements are

678 543 234 543
124 432 456 677
321 564 432 654
