Question

In C++

A new author is in the process of negotiating a contract for a new romance novel. The publisher is offering three options.

• In the first option, the author is paid $5,000 upon delivery of the final manuscript and $20,000 when the novel is published.
• In the second option, the author is paid 12.5% of the net price of the novel for each copy of the novel sold.
• In the third option, the author is paid 10% of the net price for the first 4,000 copies sold, and 14% of the net price for the copies sold over 4,000.

The author has some idea about the number of copies that will be sold and would like to have an estimate of the royalties generated under each option.

Instructions

Write a program that prompts the author to enter:

1. The estimated number of copies that will be sold.
2. The net price of each copy of the novel

The program then outputs:

1. The royalties under each option
2. The best option the author could choose.
   • Ex. If option 1 is the best, output Option 1 is the best

(Use appropriate named constants to store the special values such as royalty rates and fixed royalties.)

Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2.

Example input:

120
22.99

Expected Output:

25000.0

344.8

275.8

Option 1 is the best

Answer 1

#include <iostream>

using namespace std;

int main()
{
double copies,price,second,third; //Declaring variables
cout<<"\nEnter no of estimated copies: ";
cin>>copies; //Taking no of copies from user
cout<<"\nEnter net price of each copy of the novel: ";
cin>>price; //Taking price from user
cout<<"\nOption 1: $25000"; //Printing option 1
second = price * 0.125 * copies; //Calculating option 2
cout<<"\nOption 2: $"<<second; //Printing option 2
if(copies<4000)
third = price * 0.10 * copies; //Calculating option 3
else
third = (price * 0.10 * 4000) + (price * 0.14 * (copies-4000)); //Calculating option 3
cout<<"\nOption 3: $"<<third; //Printing option 3
if(25000>second && 25000>third) //Checking which option is best
cout<<"\nOption 1 is best";
else if(second>third)
cout<<"\nOption 2 is best";
else
cout<<"\nOption 3 is best";
  

return 0;
}

Output:-
