How to calculate 2x2 Matrix in Cplusplus.

In this program we  discuss 2x2 Matrix in Cplusplus. In the matrix multiplication AB, the number of columns in matrix A must be equal to the number of rows in matrix B. The resulting product matrix will have the same number of rows as matrix A and the same number of columns as B.

Source Code:

#include<iostream>

using namespace std;

int main()

{

             int a[2][2];

             cout<<"Enter Number\n";

            for(int row=0;row<2;row++)

            {

                        for(int col=0;col<2;col++)

                        {

                                    cin>>a[row][col];

                        }

            cout<<endl;

            }

            cout<<"determinant:";

                        cout<<a[0][0]*a[1][1]-a[0][1]*a[1][0]<<endl;

                        return 0;

}
