Answer 1

#include <iostream>
using namespace std;

const double PAYMENT_RATE = 8.0;
const double KWSF = 0.1;
const int N = 5;

void salary1(double hours[N]) {
    double payment, tot_payment=0.0;


    for (int i=0; i<N; i++) {
        payment = (hours[i] * PAYMENT_RATE) * (1 - KWSF);
        cout << i+1 << " employee salary is RM" << payment << endl;
        tot_payment += payment;
    }
    cout << endl << "Average salary is " << tot_payment / N << endl << endl;
}


void salary2(double hours[N]) {
    double payment, tot_payment=0.0;
    int i=0;

    while(i<N) {
        payment = (hours[i] * PAYMENT_RATE) * (1 - KWSF);
        cout << i+1 << " employee salary is RM" << payment << endl;
        tot_payment += payment;
        i++;
    }
    cout << endl << "Average salary is " << tot_payment / N << endl << endl;
}


void salary3(double hours[N]) {
    double payment, tot_payment=0.0;
    int i=0;

    do {
        payment = (hours[i] * PAYMENT_RATE) * (1 - KWSF);
        cout << i+1 << " employee salary is RM" << payment << endl;
        tot_payment += payment;
        i++;
    } while (i<N);
    cout << endl << "Average salary is " << tot_payment / N << endl << endl;
}


int main()
{
    double hours[N] = {8, 6, 8, 4, 9};

    salary1(hours);
    salary2(hours);
    salary3(hours);
}
