Prerequisite: Array in C

Arrays are used the make a list of the same data type elements and store it in contiguous memory locations. In simple words, arrays are the organization of elements of the same data types. There are many types for declaring the array i.e, 1-Dimensional arrays, 2-Dimensional arrays, and 3-Dimensional arrays.

What is Wiring?

Wiring is the concept that shows the array connected with each other and forming a new 3-Dimensional array.

3-Dimensional Array

A collection of 2-dimensional arrays, stored sequentially in storage locations in the array is called a 3-Dimensional array.

Wiring related to a 3-D array:

The original meaning of the wiring is connecting the things and also in the 3-Dimensional array it works the same, it is used for connecting the array and making the new Three-dimensional structure. Every block/element of the array is connected with each other.

In this article, we are discussing 3-dimensional arrays which are organized in the form of wiring. These 3-dimensional arrays in wiring are like matrix declarations in the array.

Example:

C

// C Program to implement 3-D // array using concept of wiring #include <stdio.h>  int main() {     int i, j, k;      // Declaration of 3-D array in form of wiring     int arr[3][3][3] = {         { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } },         { { 11, 12, 13 }, { 14, 15, 16 }, { 17, 18, 19 } },         { { 21, 22, 23 }, { 24, 25, 26 }, { 27, 28, 29 } },     };     // traversing the all the elements     for (i = 0; i < 3; i++) {         for (j = 0; j < 3; j++) {             for (k = 0; k < 3; k++) {                 // printing all elements                 // in the form of matrix                 printf("%d", arr[i][j][k]);                 printf("\t");             }             printf("\n");         }         printf("\n");     }      return 0; }

Output

1    2    3      4    5    6      7    8    9        11    12    13      14    15    16      17    18    19        21    22    23      24    25    26      27    28    29

One Dimensional Arrays in C

In C, an array is a collection of elements of the same type stored in contiguous memory locations. This organization allows efficient access to elements using their index.

Difference Between one-dimensional and two-dimensional array

Array is a data structure that is used to store variables that are of similar data types at contiguous locations. The main advantage of the array is random access and cache friendliness. There are mainly three types of the array: One Dimensional (1D) ArrayTwo Dimension (2D) ArrayMultidimensional Arr
