Three Dimensional Array Program in C++
Three dimensional (3D) array contains three for loops
in C++ programming. So, to initialize and print three dimensional array, you have to use three for loops.
Third for loop (the innermost loop) forms 1D array, Second for loop forms
2D array and the third for loop (the outermost loop) forms 3D array, as shown here
in the following program.
C++ Programming Code for Three Dimensional (3D) Array
A three dimensional (3D) array can be thought of as an array of arrays of arrays. Following is a simple C++ program to initialize
three-dimensional (3D) array of dimensions 3*4*2, then it will access some elements present in the array and display the element on the screen :
/* C++ Program - Three Dimensional Array Program */
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int arr[3][4][2] = {
{
{2, 4},
{7, 8},
{3, 4},
{5, 6}
},
{
{7, 6},
{3, 4},
{5, 3},
{2, 3}
},
{
{8, 9},
{7, 2},
{3, 4},
{5, 1}
}
};
cout<<"arr[0][0][0] = "<<arr[0][0][0]<<"\n";
cout<<"arr[0][2][1] = "<<arr[0][2][1]<<"\n";
cout<<"arr[2][3][1] = "<<arr[2][3][1]<<"\n";
getch();
}
When the above C++ program is compile and executed, it will produce the following result:
Here, the outer array has three elements, each of which is a 2-D array of four 1-D arrays, each of which contains two integers.
It means, a 1-D array of two elements is constructed first. Then four such 1-D arrays are placed one below the other to give a 2-D
array containing four rows. Then, three such 2-D arrays are placed one behind the other to yield a 3-D array containing three 2-D arrays.
