4 Dimensional Array in C/C++

Prerequisite :Array in C/C++, More on array

A four-dimensional (4D) array is an array of array of arrays of arrays or in other wordes 4D array is a array of 3D array.
More dimensions in an array means more data be held, but also means greater difficulty in managing and understanding arrays.

Declaration of a Multidimensional Array in C:

data_type array_name[i1][i2][i3][i4]………[in];
where each i is a dimension, and in is the size of final dimension.

1. int student[4][5][6][7];
int designates the array type integer.
student is the name of our 4D array.
Our array can hold 840 integer-type elements. This number is reached by multiplying the value of each dimension. In this case: 4x5x6x7=840.

2. float country[5][6][5][6][5];
Array country is a five-dimensional array.
It can hold 4500 floating-point elements (5x6x5x6x5=4500).

Program :





// C Program to input 4D Matrix and print it.
#include <stdio.h>
int main()
    // variable declaration used for indexes
    int i, j, k, l, size;
    // Array declaration
    int a[2][2][2][2];
    // size of array
    size = 2;
    // elements input
    a[0][0][0][0] = 5;
    a[0][0][0][1] = 3;
    a[0][0][1][0] = 5;
    a[0][0][1][1] = 3;
    a[0][1][0][0] = 6;
    a[0][1][0][1] = 7;
    a[0][1][1][0] = 6;
    a[0][1][1][1] = 7;
    a[1][0][0][0] = 8;
    a[1][0][0][1] = 9;
    a[1][0][1][0] = 8;
    a[1][0][1][1] = 9;
    a[1][1][0][0] = 9;
    a[1][1][0][1] = 7;
    a[1][1][1][0] = 9;
    a[1][1][1][1] = 7;
    // Printing the values
    for (i = 0; i < size; i++) {
        for (j = 0; j < size; j++) {
            for (k = 0; k < size; k++) {
                for (l = 0; l < size; l++) {
                    printf("Value of a[%d][%d][%d][%d] :- %d "
                                   i, j, k, l, a[i][j][k][l]);
    return 0;



Value of a[0][0][0][0] :- 5 
Value of a[0][0][0][1] :- 3 
Value of a[0][0][1][0] :- 5 
Value of a[0][0][1][1] :- 3 
Value of a[0][1][0][0] :- 6 
Value of a[0][1][0][1] :- 7 
Value of a[0][1][1][0] :- 6 
Value of a[0][1][1][1] :- 7 
Value of a[1][0][0][0] :- 8 
Value of a[1][0][0][1] :- 9 
Value of a[1][0][1][0] :- 8 
Value of a[1][0][1][1] :- 9 
Value of a[1][1][0][0] :- 9 
Value of a[1][1][0][1] :- 7 
Value of a[1][1][1][0] :- 9 
Value of a[1][1][1][1] :- 7

An 4D array can be used to store a collection of data, for example we input 3 coordinates & 1 time, i.e., x, y, z, t and we want to check whether there is collision between two vehicles or not.
