Algorithm of program to check if a number is even or odd. Start Initialize: number (integer) Input: User inputs 42 number = 42 Processing: Calculate 42 % 2 which equals 0 Since 0 == 0, print “The number 42 is even.” End

#include <iostream>
using namespace std;

int main() {
    // Declare a variable to store the number
    int number;
    
    // Get user input
    cout << "Enter a number: ";
    cin >> number;
    
    // Check if the number is even or odd
    if (number % 2 == 0) {
        // If the remainder when dividing by 2 is 0, the number is even
        cout << "The number " << number << " is even." << endl;
    } else {
        // If the remainder when dividing by 2 is not 0, the number is odd
        cout << "The number " << number << " is odd." << endl;
    }
    
    return 0;
}

#include <iostream>

using namespace std;

int main() {

// Declare a variable to store the number

int number;

// Get user input

cout << "Enter a number: ";

cin >> number;

// Check if the number is even or odd

if (number % 2 == 0) {

// If the remainder when dividing by 2 is 0, the number is even

cout << "The number " << number << " is even." << endl;

} else {

// If the remainder when dividing by 2 is not 0, the number is odd

cout << "The number " << number << " is odd." << endl;

}

return 0;

}
