Redo Programming Exercise $16$ of Chapter $4$ so that all the named constants are defined in a namespace royaltyRates.

Instructions for Programming Exercise $16$ of Chapter $4$ have been posted below for your convenience.

Exercise $16$

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 $12\mathrm{.}5\%$ 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. Write a program that prompts the author to enter the net price of each copy of the novel and the estimated number of copies that will be sold. The program then outputs the royalties under each option and the best option the author could choose. $($Use appropriate named constants to store the special values such as royalty rates and fixed royalties.$)$

Task #$01$: Program Executes Correctly

This is the code i have so far:

#include

#include

#include

using namespace std;

$//$ Define the namespace royaltyRates

namespace royaltyRates $\{$

const double CHOICE$\_$ONE$\_$ROYALTIES $=25000\mathrm{.}0$;

const double CHOICE$\_$TWO$\_$ROYALTY$\_$RATE $=0\mathrm{.}125$;

const double CHOICE$\_$THREE$\_$ROYALTY$\_$RATE$\_$UNDER$\_4000=0\mathrm{.}10$;

const double CHOICE$\_$THREE$\_$ROYALTY$\_$RATE$\_$OVER$\_4000=0\mathrm{.}14$;

const int CHOICE$\_$THREE$\_$THRESHOLD $=4000$;

$\}$

int main$()\{$

$//$ Declare variables

double bookCost;

int soldCopies;

double option$\_$two$\_$royalties;

double option$\_$three$\_$royalties;

string bestoption;

$//$ Read cost of book

cout $<<$ "Enter the net price of each copy of the novel: $"$;

cin $>>$ bookCost;

$//$ Read number of copies sold

cout $<<$ "Enter the estimated number of copies that will be sold: $"$;

cin $>>$ soldCopies;

$//$ Calculate the option $2$ royalties amount

option$\_$two$\_$royalties $=($bookCost $*$ royaltyRates::CHOICE$\_$TWO$\_$ROYALTY$\_$RATE$)*$ soldCopies;

$//$ Calculate the option $3$ royalties amount

if $($soldCopies $<=$ royaltyRates::CHOICE$\_$THREE$\_$THRESHOLD$)\{$

option$\_$three$\_$royalties $=$ bookCost $*$ soldCopies $*$ royaltyRates::CHOICE$\_$THREE$\_$ROYALTY$\_$RATE$\_$UNDER$\_4000$;

$\}$ else $\{$

option$\_$three$\_$royalties $=($bookCost $*$ royaltyRates::CHOICE$\_$THREE$\_$THRESHOLD $*$ royaltyRates::CHOICE$\_$THREE$\_$ROYALTY$\_$RATE$\_$UNDER$\_4000)+$

$($bookCost $*($soldCopies $-$ royaltyRates::CHOICE$\_$THREE$\_$THRESHOLD$)*$ royaltyRates::CHOICE$\_$THREE$\_$ROYALTY$\_$RATE$\_$OVER$\_4000)$;

$\}$

$//$ Determine the best option

if $($royaltyRates::CHOICE$\_$ONE$\_$ROYALTIES $>$ option$\_$two$\_$royalties && royaltyRates::CHOICE$\_$ONE$\_$ROYALTIES $>$ option$\_$three$\_$royalties$)\{$

bestoption $=$ "Option $1"$;

$\}$ else if $($option$\_$two$\_$royalties $>$ royaltyRates::CHOICE$\_$ONE$\_$ROYALTIES && option$\_$two$\_$royalties $>$ option$\_$three$\_$royalties$)\{$

bestoption $=$ "Option $2"$;

$\}$ else $\{$

bestoption $=$ "Option $3"$;

$\}$

$//$ Print the three royalties

cout $<<$ fixed $<<$ setprecision$(2)$;

cout $<<"[\text{'}$Royalty option$1$: $"<<$ royaltyRates::CHOICE$\_$ONE$\_$ROYALTIES $<<"\text{'},"$;

cout $<<"\text{'}$Royalty option$2$: $"<<$ option$\_$two$\_$royalties $<<"\text{'},"$;

cout $<<"\text{'}$Royalty option$3$: $"<<$ option$\_$three$\_$royalties $<<"\text{'}]"<<$ endl;

$//$ Print the best option

cout $<<$ "The best option is $"<<$ bestoption $<<"."<<$ endl;

return $0$;

$\}$

and these are the objectives within task $1.$

as you can see i have two out of three but cant figure out why task $2$ keeps failing and when i put it in visual studios i have no errors. very confused and need help please!
