Suppose you are given a square matrix of size n x n, write a program to determine if this is an identity matrix. 2D array

Using Visual Studio 2015

===============================================================

#include<iostream>
using namespace std;
#include<conio.h>
void main()
{
 int array1[2][2];
 for (int i = 0; i <= 1; i++)
 {
  for (int j = 0; j <= 1; j++)
  {
   cout<<"Enter the integers=";
   cin>>array1[i][j];
  }
 }
 for (int i = 0; i <= 1; i++)
 {
 for(int j = 0; j <= 1; j++)
 {
 cout<<array1[i][j];
 }
 cout<<endl;
  }
 if (array1[0][0] == 1 && array1[1][1] == 1 && array1[0][1] == 0 && array1[1][0] == 0)
 {
  cout << "\nIt is an identity matrix";
 }
 else
 {
  cout << "\nNot an identity matrix";
 }
 _getche();
}
