MULTI DIMENSIONAL ARRAYS

MULTI DIMENSIONAL ARRAYS

            Like one-dimensional and two dimensional arrays C language also allows multi-dimensional arrays. Arrays with three or more dimensions are called multi-dimensional arrays.

A multi dimensional array can be declared as follows:-

Syntax:

            datatype variable[size1][size2]……[size n];

ex:  int a[4][5][4];

Initializing values to multidimensional arrays.

Eg:-

            int a[3][3][3]={{{1,2,3},

             {4,5,6},

             {7,8,9}},

          {{10,11,12},

         {13,14,15}

         {16,17,18}},

                                    {{19,20,21},

         {22,23,24},

       {25,26,27}}};

Sample program that reads and prints elements of a three dimensional array.

#include<stdio.h>

#include<conio.h>

void main()

{

 int i,j,k,a[10][10][10],m,n,p;

 clrscr();

 printf("\n Enter order of matrix: ");

 scanf("%d%d%d",&m,&n,&p);

 printf(" Enter elements: ");

 for(i=0;i<m;i++)

 {

  for(j=0;j<n;j++)

  {

   for(k=0;k<p;k++)

   {

    scanf("%d",&a[i][j][k]);

   }

  }

 }

 printf(" Elements in matrix form are :");

 for(i=0;i<m;i++)

 {

  printf("\n");

  for(j=0;j<n;j++)

  {

   for(k=0;k<p;k++)

   {

    printf("%d\t",a[i][j][k]);

   }

   printf("\n");

  }

 }

 getch( );

}

Output

 Enter order of matrix: 2

2

2

 Enter elements: 1

8

 Elements in matrix form are :

1       2

3       4

5       6
