Frequencies of even and odd numbers in a matrix

Given a matrix of order m*n then the task is to find the frequency of even and odd numbers in matrix
Examples:

Input : m = 3, n = 3
{ 1, 2, 3 },
{ 4, 5, 6 },
{ 7, 8, 9 }
Output : Frequency of odd number =  5
Frequency of even number = 4

Input :   m = 3, n = 3
{ 10, 11, 12 },
{ 13, 14, 15 },
{ 16, 17, 18 }
Output : Frequency of odd number  =  4
Frequency of even number  = 5

CPP

 // C++ Program to Find the frequency // of even and odd numbers in a matrix #include using namespace std;    #define MAX 100    // function for calculating frequency void freq(int ar[][MAX], int m, int n) {     int even = 0, odd = 0;            for (int i = 0; i < m; ++i)     {         for (int j = 0; j < n; ++j)         {             // modulo by 2 to check             // even and odd             if ((ar[i][j] % 2) == 0)                 ++even;             else                 ++odd;         }     }            // print Frequency of numbers     printf(" Frequency of odd number = %d \n", odd);     printf(" Frequency of even number = %d \n", even); }    // Driver code int main() {     int m = 3, n = 3;                int array[][MAX] = { { 1, 2, 3 },                         { 4, 5, 6 },                         { 7, 8, 9 } };        freq(array, m, n);     return 0; }

Output:

Frequency of odd number = 5
Frequency of even number = 4
