I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.

#include <iostream>
using namespace std;
 
int main()
{
    static int Arr[10][10];
    int i, j, x, y;
    int    even,  odd;
 
    cout<<"Enter the order of the matrix \n";
    //Inputing elements in matrix from user
    cin>>x;
    cin>>y;
    cout<<"Enter the coefficients of matrix\n";
 
    /* Assuming that there are 0 even and odd elements */
    even = 0;
    odd = 0;
    for (i = 0; i < x; ++i)
    {
            for (j = 0; j < y; ++j)
            {
                 cin>>Arr[i][j];
                 if ((Arr[i][j] % 2) == 0)
                 {
                     ++even;
                 }
                 else
                     ++odd;
             }
    }
    // Printing user's given matrix
    cout<<"The given matrix is \n";
    for (i = 0; i < x; ++i)
    {
        for (j = 0; j < y; ++j)
        {
            cout<<" "<<Arr[i][j];
        }
        cout<<"\n";
    }
    // Printing occurance of even and odd numbers
    cout<<"\n The frequency of occurance of odd number  = "<<odd <<"\n";
    cout<<"\n The frequency of occurance of even number  = "<<even <<"\n";
}

Result:

Enter the order of the matrix 

3

3

Enter the coefficients of matrix

1

2

3

4

5

6

7

8

9

The given matrix is 

 1 2 3

 4 5 6

 7 8 9

 The frequency of occurance of odd number  = 5

 The frequency of occurance of even number  = 4
