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
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.
Syntax
Data_type Array_name[size 1][size 2][size 3];
int marks[2][3][4];
char alphabet[3][4][5];
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;
