In the C++ programming language, an array is a fixed sequenced collection of the element of the same data types. an array can be used to represent a list of number(int) or name (string) or other data type of similar elements. It is one of the ways of simply a grouping of similar types of data of single variables names.

Three types of arrays in C programming language

1. One dimensional array
2. Two-dimensional array
3. multidimensional array

Three dim Array

Now we will know three dim Array in C++. C++ programming supports multidimensional Array. the Multidimensional array is also called as matrix Here we will declare the three-dim array

3 D array

Explanation of three dimenssion Array

A 3d Array is essentially an array of arrays of arrays or collection of 2 D Arrays.

The array of 2 D array

Declaration three dim Array

Syntax

Data _Type Array_name[size1][size2][size3];

Example1 – integer Array

int marks[2][3][4];

Example2 – character Array

char volume[20][30][40];

Initialization of Three dim Array

Method 1

Initialize using standred method

We can initialized every element in three dim array

marks[0][0][0]=45; //Cell address of marks[][][] have one elemet value is 45

Example

#include <iostream>
#include <conio.h>

using namespace std;
int main()
{
    int marks[2][2][3];//array declaration

    marks[0][0][0]=78;  //initialization of array of 2 D array
    marks[0][0][1]=68;
    marks[0][0][2]=35;
    marks[0][1][0]=79;
    marks[0][1][1]=52;
    marks[0][1][2]=49;
    marks[1][0][0]=45;
    marks[1][0][1]=73;
    marks[1][0][2]=63;
    marks[1][1][0]=45;
    marks[1][1][1]=73;
    marks[1][1][2]=63;

    //Display elements
    cout << "Array elements display here\n" << endl;
    cout << marks[0][0][0] << endl;
    cout << marks[0][0][1] << endl;
    cout << marks[0][0][2] << endl;
    cout << marks[0][1][0] << endl;
    cout << marks[0][1][1] << endl;
    cout << marks[0][1][2] << endl;
    cout << marks[1][0][0] << endl;
    cout << marks[1][0][1] << endl;
    cout << marks[1][0][2] << endl;
    cout << marks[1][1][0] << endl;
    cout << marks[1][1][1] << endl;
    cout << marks[1][1][2] << endl;
    getch();
    return 0;
}

When the above code is executed it produces the following result

Initialized during the declaration

int marks[2][3][4]={
{{45,65,34,78},{78,56,32,23},{68,57,37,89}},
{{87,43,68,53},{“62,67,43,87},{54,67,90,87}}

};

Program 1

#include <iostream>

using namespace std;

int main()
{
int i, j, k;
int arr[3][3][3]=
{
{
{14, 16, 13},
{14, 15, 19},
{17, 18, 89}
},
{
{51, 22, 73},
{24, 95, 26},
{57, 28, 79}
},
{
{33, 30, 39},
{35, 45, 56},
{99, 38, 37}
},
};
cout<<(“:::3D Array Elements:::nn”);
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
for(k=0;k<3;k++)
{
cout<<(arr[i][j][k]);
}
cout<<(“n”);
}
cout<<(“n”);
}
}

When the above code is executed it produces the following result

Output

Initialize and display elements using loops

Using for loop

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int arr[2][2][3],i,j,k;

    cout << "Enter the numbers for 3 D array" << endl;
    for(i=0; i<2; i++){
        for(j=0; j<2; j++){
            for(k=0; k<3; k++){
        cin>>arr[i][j][k];//store array elements
    }
    }
    }

    cout << "\nYour entered elements display here\n" << endl;
    for(i=0; i<2; i++){
        for(j=0; j<2; j++){//display the array elements
           for(k=0; k<3; k++){//display the array elements
        cout << "you entered to index arr["<<i<<"]["<<j<<"]["<<k<<"]: "<<arr[i][j][k] <<endl;
    }
    }
    }
    getch();
    return 0;
}

When the above code is executed it produces the following result

Output

Using while loop

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int arr[2][2][3],i,j,k;

    cout << "Enter the numbers for 3 D array" << endl;
    i=0;
    while(i<2){
            j=0;
        while(j<2){
            k=0;
            while(k<3){
        cin>>arr[i][j][k];//store array elements
     k++;
    }
     j++;
    }
     i++;
    }

    cout << "\nYour entered elements display here\n" << endl;
    i=0;
    while(i<2){
            j=0;
        while(j<2){//display the array elements
                k=0;
           while(k<3){//display the array elements
        cout << "you entered to index arr["<<i<<"]["<<j<<"]["<<k<<"]: "<<arr[i][j][k] <<endl;
        k++;
    }
     j++;
    }
    i++;
    }
    getch();
    return 0;
}

When the above code is executed it produces the following result

Output

Using the do-while loop

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int arr[2][2][3],i,j,k;

    cout << "Enter the numbers for 3 D array" << endl;
    i=0;
    do{
            j=0;
        do{
            k=0;
           do{
        cin>>arr[i][j][k];//store array elements
     k++;
    } while(k<3);
     j++;
    }while(j<2);
     i++;
    }while(i<2);

    cout << "\nYour entered elements display here\n" << endl;
    i=0;
    do{
            j=0;
        do{//display the array elements
                k=0;
           do{//display the array elements
        cout << "you entered to index arr["<<i<<"]["<<j<<"]["<<k<<"]: "<<arr[i][j][k] <<endl;
        k++;
    }while(k<3);
     j++;
    }while(j<2);
    i++;
    }while(i<2);
    getch();
    return 0;
}

When the above code is executed it produces the following result
