// Sum of Numbers Up To 10
#include <iostream>
using namespace std;

int main() {
    // Step 1: Initialize a variable to store the sum
    // It's crucial to start with 0 so the first addition is correct.
    int sum = 0;

    // Step 2: Use a for loop to iterate from 1 to 10
    // The loop variable 'i' will take values 1, 2, ..., 10.
    for (int i = 1; i <= 10; ++i) {
        // Step 3: Add the current number 'i' to the sum
        sum = sum + i; // This can also be written as sum += i;
    }

    // Step 4: Print the final sum to the console
    cout << "The sum of numbers from 1 to 10 is: " << sum << endl;

    return 0;
