Multidimensional Array

Multidimensional array is also known as rectangular arrays. It can be two dimensional or three dimensional. The data is stored in tabular form (row, column) which is also known as matrix. To create multidimensional array, we need to use [][] after array name.
Before studying Multidimensional array, we need to be clear with one dimensional array. Below we are telling the system to create new array memory space of given rows and columns.

Syntax
datatype arrayName[row][column];

TIP
When it comes to multidimensional array always declare memory space first and use index value of row and coloumn in order to assign the values so that it will not be confusing.

CODE

EG 1 . Creating 2 dimensional array with 2 rows and 3 coloumns to store name of cricket players.

#include <iostream>
using namespace std;
int main() {
    string cricketPlayers[2][3];
    cricketPlayers[0][0] = "Sachin";
    cricketPlayers[0][1] = "Ramesh";
    cricketPlayers[0][2] = "Tendulkar";
    cricketPlayers[1][0] = "Mahendra";
    cricketPlayers[1][1] = "Singh";
    cricketPlayers[1][2] = "Dhoni";
}

CODE EXPLANATION
In the above code, We declared a 2 dimensional array with 2 rows and 3 columns. First we declared memory space then we called individual index number of row and column in order to assign values inside. Once after assigning the values our memory space will look like above diagram.

Exercises
1. Create 2 dimensional char[] with 4 rows and 5 columns. Visualize how memory allocation, naming will takes place with the help of diagram.
