Three dimension Array in Cpp language

Three dimension Array in Cpp language

In this tutorial, We will learn  about Three dimension Array in Cpp language

In the C++ Programming Language, an array is a fixed sequential collection of elements of the same data type. An array can be used to represent a list of numbers(int) or names (string) or other data type of similar elements. It is one of the ways of grouping similar type data with single variables names.

Three types of arrays in Cpp programming language

1.  One dimensional array

2. Two-dimensional array

3. Multi-dimensional array

 

Three dimensional Array


Now, we will look at three dimensional Array in C++. C++ programming supports multidimensional Array. The multidimensional array is also called a matrix. Here, we will declare the three-dimensional array.

Declaration of Three dimension Array

Syntax

Data_type Array_name[size 1][size 2][size 3];
Example 1 –  integer Array
int marks[2][3][4];
Example 2 – char Array
char alphabet[3][4][5];
Initialization of three dimension array in C++
int marks[2][3][4]={
      {{34,56,76,54},{98,53,86,34},{23,45,67,89}},
      {{8,87,76,65},{75,46,52,32},{78,65,84,62}}
};

Examples

Access elements in the array

insert elements from the array in C++

array name[index][index][index]=value;
marks[0][0][0]=45;

display elements from the array in C++

cout<<array name[index][index][index];
cout<<marks[0][0][0];

Program 1

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

int main()
{
    int marks[2][2][3];
    //array index must be index to Zero
    marks[0][0][0]=45;
    marks[0][0][1]=67;
    marks[0][0][2]=23;
    marks[0][1][0]=98;
    marks[0][1][1]=15;
    marks[0][1][2]=70;
    marks[1][0][0]=87;
    marks[1][0][1]=76;
    marks[1][0][2]=65;
    marks[1][1][0]=63;
    marks[1][1][1]=50;
    marks[1][1][2]=37;
    cout << "marks[0][0][0] :" << marks[0][0][0]<<"\n";
    cout << "marks[0][0][1] :" << marks[0][0][1]<<"\n";
    cout << "marks[0][0][2] :" << marks[0][0][2]<<"\n";
    cout << "marks[0][1][0] :" << marks[0][1][0]<<"\n";
    cout << "marks[0][1][1] :" << marks[0][1][1]<<"\n";
    cout << "marks[0][1][2] :" << marks[0][1][2]<<"\n";
    cout << "marks[1][0][0] :" << marks[1][0][0]<<"\n";
    cout << "marks[1][0][1] :" << marks[1][0][1]<<"\n";
    cout << "marks[1][0][2] :" << marks[1][0][2]<<"\n";
    cout << "marks[1][1][0] :" << marks[1][1][0]<<"\n";
    cout << "marks[1][1][1] :" << marks[1][1][1]<<"\n";
    cout << "marks[1][1][2] :" << marks[1][1][2]<<"\n";
    getch();
    return 0;
}

When the above code is executed, it produces the following results:

    marks[0][0][0]=45;
    marks[0][0][1]=67;
    marks[0][0][2]=23;
    marks[0][1][0]=98;
    marks[0][1][1]=15;
    marks[0][1][2]=70;
    marks[1][0][0]=87;
    marks[1][0][1]=76;
    marks[1][0][2]=65;
    marks[1][1][0]=63;
    marks[1][1][1]=50;
    marks[1][1][2]=37;

 

Program 2

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

int main()
{

    cout << "Three dimension array in C++" << endl;
    int marks[2][2][3]={
        {
            {56,78,67},{56,78,43}},
            {{26,74,76},{36,58,90}},
        };
        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 results:

using namespace std;
int main()
{   int i,j,k;
    int marks[3][3][3]=
    {               //declaration and initiation
                {
                    {56,78,56},
                    {54,34,32},
                    {43,26,92},
                    },
                {   {48,94,62},
                    {41,39,66},
                    {68,40,90},
                    },
                {
                    {20,67,84},
                    {52,51,72},
                    {60,53,59},}
                    };
cout<<("3 D Array element\n")<<endl;
for(i=0;i<3;i++)
{
    for(j=0;j<3;j++)
    {
        for(k=0;k<3;k++){
            cout <<(marks[i][j][k]);
        }
        cout <<("\n");
    }
    cout <<("\n");
}
cout << "End of the program" << endl;
return 0;

54,34,32
43,26,92

48,94,62
41,39,66
68,40,90
      
20,67,84
52,51,72
60,53,59

End of the program

    for(int i=0; i<=1; i++){//input value using for loop
            for(int j=0; j<=1; j++){
                    for(int k=0; k<=2; k++){
       cout << "Name["<<i<<"]["<<j<<"]["<<k<<"] :";
    cin>> Name[i][j][k];//Ask input for element of array
                    }
            }
    }
    cout << "\nyour input name here" << endl;
    for(int i=0; i<=1; i++){//Display value using for loop
            for(int j=0; j<=1; j++){

    cout << "End of program" << endl;
    getch();
    return 0;
}

 

When the above code is executed, it produces the following results:

Enter names
names[0][0][0]=Saru
names[0][0][1]=Kuna
names[0][1][0]=Joe
names[0][1][1]=Jhon
names[0][2][0]=Pilib
names[0][2][1]=Para
names[1][0][0]=Mohi
names[1][0][1]=Suba
names[1][1][0]=Guru
names[1][1][1]=Nila
names[1][2][0]=Mala
names[1][2][1]=Mathu

This names are stored in array
names[0][0][0]=Saru
names[0][0][1]=Kuna
names[0][1][0]=Joe
names[0][1][1]=Jhon
names[0][2][0]=Pilib
names[0][2][1]=Para
names[1][0][0]=Mohi
names[1][0][1]=Suba
names[1][1][0]=Guru
names[1][1][1]=Nila
