Question

C++:

Write correct C++ code for a nested if-else if-else structure that will output a message based on the logic below.

A buyer can pay immediately or be billed. If paid immediately, then display "a 5% discount is applied." If billed, then display "a 2% discount is applied" if it is paid in 30 days. If between 30 and 60 days, display "there is no discount." If over 60 days, then display "a 3% surcharge is added to the bill."

You do not need to declare the variables or assign them values; just write the code for the nested if-else structure itself and the cout statements to display the messages only.

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

#include <iostream>

using namespace std;

double processPayment(double total, int action);

int main()

{

double total;

int action;

cout << "Enter total amount to be paid:" << endl;

cin >> total;

cout<<"Enter your action 1. immediately paid 2. Billed and will pay in 30 days 3. Others"<<endl;

cin >> action;

total = processPayment(total, action);

cout <<"Total amount to be paid after applying respective discount :"<<total<<endl;

return 0;

}

double processPayment(double total, int action) {

if(action == 1)

{

total = total - (total * 5.0/100.0);

}

else if(action == 2){

total = total - (total * 2.0/100.0);

}

else

{

total = total + (total * 3.0/100.0);

}

return total;

}
