Question

Write a value- return function which accepts the cost and the tip percentage (tipPercentage) as parameters. The function must calculate the total meal amount that the customer must pay including the tip. Thus, values of tipPercentage can be 15 representing 15%, 18 representing 18%, and 20 representing 20%. An example of the cost of the meal with 15% is as follows : dinner cost * 0.15 + dinner cost.

Double costOfMeal (double price, int tipPercentag) {

Answer 1

C++ PROGRAM

#include<iostream>

using namespace std;

// implement costOfMeal()

double costOfMeal(double price,int tipPercentag)

{

return price*(tipPercentag/100.0)+price; // return total cost of Meals

}

int main()

{

// declare variables

double price;

int tip;

cout<<"Enter Price: "; cin>>price; // read price

cout<<"Enter Tip: "; cin>>tip; // read tip cost

cout<<costOfMeal(price,tip)<<endl; // calling costOfMeal() function

return 0;

}

OUTPUT-1

Enter Price: 55.5
Enter Tip: 18
65.49

OUTPUT-2

Enter Price: 65.5
Enter Tip: 18
77.29

OUTPUT-3

Enter Price: 95.3
Enter Tip: 20
114.36
