Multi dimensional Array in C++ 

An array containing more than two dimensions is called multi-dimensional array. We can use more than two pairs of brackets to specify the size or refer any array element

Syntax :

<Type> Arr_name[s1][s2][s3]……………….;

Here, Type refers to any valid data type of C++. It can be any valid data type of C++ like int, float, char, structure, union, class etc.

Arr_name  specifies the name of array as defined by the programmer. The name of array must follow all the rules of a valid identifier of C++.

[ ] Square brackets are known as subscript, they are used to declare size of array within them.

s1,s2,s3,…. specify the dimensions in the multidimensional array. They should be integer values.

#include<iostream> 
using namespace std;
int main()
 {
  int i,j,k;
  int arr3D[2][2][2]={3,4,5,6,8,9,7,1};
  cout<<"\nArray is=";
  for(i=0;i<2;i++)
  {
   for(j=0;j<2;j++)
   {
     for(k=0;k<2;k++)
     {
       cout<<endl<<arr3D[i][j][k];
     }
   }
 }
return 0;
}
