#include <iostream>
using namespace std;

int main() {
    // Example using a for loop
    // The for loop is typically used when you know in advance how many times you want to execute a statement or a block of statements.
    //for (int i = 1; i <= 5; i++): This loop starts with i set to 1. It continues to run as long as i is less than or equal to 5, incrementing i by 1 after each iteration.
    //This is useful when you know how many times you need to execute the loop.
   
    cout << "Using for loop:" << endl;
    for (int i = 1; i <= 5; i++) {
        // Loop will run 5 times, printing the value of i each time
        cout << i << " ";
    }
    cout << endl;

    // Example using a while loop
    // The while loop is used when you want to repeat a block of code while a certain condition is true.
    //int j = 1; while (j <= 5): The loop starts with j set to 1. It checks the condition j <= 5 before each iteration, and as long as this condition is true, the loop continues to execute.
    //After each iteration, j is incremented.
    //Use a while loop when the number of iterations is not known beforehand and depends on some condition.
    
    cout << "Using while loop:" << endl;
    int j = 1;  // Initialize the loop control variable
    while (j <= 5) {
        // Loop will run as long as j is less than or equal to 5
        cout << j << " ";
        j++;  // Increment the loop control variable
    }
    cout << endl;

    // Example using a do-while loop
    // The do-while loop is similar to the while loop, but it guarantees that the loop body is executed at least once, even if the condition is false initially.
    //int k = 1; do { ... } while (k <= 5): The loop starts with k set to 1. The body of the loop executes at least once before the condition k <= 5 is checked.
    //If the condition is true, the loop continues; otherwise, it stops.
    //Use a do-while loop when you want the loop body to execute at least once, regardless of the condition.
    
    
    cout << "Using do-while loop:" << endl;
    int k = 1;  // Initialize the loop control variable
    do {
        // Loop will run at least once, printing the value of k
        cout << k << " ";
        k++;  // Increment the loop control variable
    } while (k <= 5);  // Continue looping as long as k is less than or equal to 5
    cout << endl;

    return 0;
