Answer to Question #333104 in C++ for Padi

Question

A bookshop gives discount to customers as follows: • Students get 10% discount, • Book dealers get 12% discount and • Pensioners get 15% discount. • All other customers get 10% discount only if their total purchases are more than R200. You are requested to write two versions of a program that calculates and displays the final amount that is due, after discount. (i) The first version of the program uses a switch statement to implement the above program. (ii) The second version of the program uses nested-if statements. Hint: Use the following variables: float amount; // the amount due before discount char customer Type; // the type of customer: 'S' (student) or // 'D' (dealer) or 'P' (pensioner) or

#include <iostream>

using namespace std;

int main() {
    float amount;
    char Type;
    int discount=0;
    
    cout << "Enter customer Type (S -  student, D - dealer, P - pensioner): ";
    cin >> Type;
    cout<<"Enter amount: ";
    cin>>amount;
    
    switch(Type){
