Two Dimensional array can be defined as a multidimensional array in C++ program. Two Dimensional Array represented as the collection of rows and columns.

Declaration of Two Dimensional Array:

To declare the 2D array in C++ programming language.

Syntax:-

Data_type Array_name[Row_size][Column_size];

Example:-

int a[3][2];

Here, a is Two-dimensional array, this array can hold 6 elements.

Initialization of Two Dimensional Array:

Multidimensional arrays initialized by specifying bracketed values for every row.

int score[3][2] = {{100, 221}, {59, 54},{10, 21}};

Example:-

#include <iostream>   
using namespace std;
  
int main(){      
    // 3 rows & 2 columns 
    int score[3][2] = {{100, 221}, {59, 54},{10, 21}};  
    for(int i=0; i<3; i++){ 
    	for(int j=0; j<2; j++){     
            cout <<	" Element[" << i << "][" << j << "]= " << score[i][j] << endl; 
         }    
    }
    return 0;    
}
