Example: Frequency of Odd and Even Numbers in a Matrix in C++

// Frequency of Odd and Even Numbers in a Matrix
#include <iostream>

int main() {
    // Step 1: Declare and initialize the matrix
    const int ROWS = 3;
    const int COLS = 3;
    int matrix[ROWS][COLS] = {
        {1, 2, 3},
        {4, 5, 6},
        {7, 8, 9}
    };

    // Step 2: Initialize counters for odd and even numbers
    int oddCount = 0;
    int evenCount = 0;

    // Step 3: Iterate through the matrix
    for (int i = 0; i < ROWS; ++i) {
        for (int j = 0; j < COLS; ++j) {
            // Step 4: Check if the current element is even or odd
            if (matrix[i][j] % 2 == 0) {
                evenCount++; // Increment even count if remainder is 0
            } else {
                oddCount++;  // Increment odd count otherwise
            }
        }
    }

    // Step 5: Display the results
    std::cout << "Original Matrix:\n";
    for (int i = 0; i < ROWS; ++i) {
        for (int j = 0; j < COLS; ++j) {
            std::cout << matrix[i][j] << " ";
        }
        std::cout << std::endl;
    }
    std::cout << "\nFrequency of Odd Numbers: " << oddCount << std::endl;
    std::cout << "Frequency of Even Numbers: " << evenCount << std::endl;

    return 0;
