Question
Markup:
Please hand in your source code and runs to test valid and invalid data.
Write a program that asks the user to enter an item’s wholesale cost and its markup percentage. It should then display the item’s retail price. For example:
If an item’s wholesale cost is 5.00 and its markup percentage is 100%, then the item’s retail price is 10.00.
If an item’s wholesale cost is 5.00 and its markup percentage is 50%, then the item’s retail price is 7.50.
The program should have a function which enters and returns valid data the wholesale cost and its markup percentage.
void getData(double&,double&);
The program should have a function named
double calculateRetail(double,double);
that receives the wholesale cost and the markup percentage as arguments, and returns the retail price of the item.
The program should have a function to display the results given the wholesale cost, the markup percentage and the retail price.
void Display(double,double,double);
Input validation: Do not accept a negative values for either the wholesale cost of the item or the markup percentage. .
Please hand in your source code and runs to test valid and invalid data.
Explanation / Answer
Please find my implementation.
#include <iostream>
using namespace std;
void getData(double&,double&);
double calculateRetail(double,double);
void Display(double,double,double);
int main() {
double whole, markup, retail;
getData(whole, markup);
retail = calculateRetail(whole, markup);
Display(whole, markup, retail);
return 0;
}
void getData(double &whole,double &markup) {
cout<<"Enter wholesale price: ";
cin>>whole;
cout<<"Enter markup percentage: ";
cin>>markup;
}
double calculateRetail(double whole,double markup) {
return whole + (whole*markup)/100;
}
void Display(double whole,double markup,double retail) {
cout<<"Retail price of item is "<<retail<<" whose wholesale price is "<<whole<<", and markup is "<<markup<<endl;
}
