C++ Program for 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<bits/stdc++.h>using namespace std; #define MAX 100 // function for calculating frequencyvoid 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 ", odd); printf(" Frequency of even number = %d ", even);} // Driver codeint 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
