Example: Find Largest Number Among Three in C++

// Find Largest Number Among Three
#include <iostream> // Required for input/output operations
using namespace std; // Use standard namespace

int main() {
    // Step 1: Declare three integer variables to store the numbers
    int num1, num2, num3;

    // Step 2: Prompt the user to enter three numbers
    cout << "Enter three numbers: ";

    // Step 3: Read the three numbers from the user
    cin >> num1 >> num2 >> num3;

    // Step 4: Use if-else if-else to find the largest number
    if (num1 >= num2 && num1 >= num3) {
        // If num1 is greater than or equal to both num2 and num3, then num1 is the largest
        cout << "The largest number is: " << num1 << endl;
    } else if (num2 >= num1 && num2 >= num3) {
        // If num2 is greater than or equal to both num1 and num3, then num2 is the largest
        cout << "The largest number is: " << num2 << endl;
    } else {
        // If neither num1 nor num2 is the largest, then num3 must be the largest
        cout << "The largest number is: " << num3 << endl;
    }

    return 0; // Indicate successful program execution
