Answer 1

#include <iostream>
using namespace std;

int main() {
    int start, end, i;
    int choice;

    cout << "Looping Statements:" << endl;
    cout << "1 - while loop" << endl;
    cout << "2 - do-while loop" << endl;
    cout << "3 - for loop" << endl;
    cout << endl << "Enter the number of looping statement: ";
    cin >> choice;

    cout << endl << "Enter Starting Number: ";
    cin >> start;
    cout <<"Enter Ending Number: ";
    cin >> end;

    if (choice == 1) {
        i = start;
        while (i <= end) {
            cout << i << ",";
            i++;
        }
    }
    else if (choice == 2) {
        i = start;
        do {
            cout << i << ",";
            i++;
        } while (i <= end);
    }
    else if (choice == 3) {
        for  (i=start; i<=end; i++) {
            cout << i << ",";
        }
    }
    else {
        cout << "Incorrect choice";
    }

    return 0;
}
