how to add two matrices using arrays in c++

#include<iostream>

#include<conio.h>

using namespace std;

int main()

       int matrix_a[3][3], matrix_b[3][3], matrix_c[3][3], row = 0, column = 0;

       cout << "\n\n\t __ Matrix Addition __\t\t\tM(Rows), N(Colomn)";

       cout << "\n\n  Elements for First Matrix  - \n";

                                        

       for(row = 0; row < 3; row++)
