Day 2: Operators

Objective

In this challenge, you'll work with arithmetic operators. Check out the Tutorial tab for learning materials and an instructional video!

Task

Given the meal price (base cost of a meal), tip percent (the percentage of the meal price being added as tip), and tax percent (the percentage of the meal price being added as tax) for a meal, find and print the meal's total cost.

Note: Be sure to use precise values for your calculations, or you may end up with an incorrectly rounded result!

Input Format

There are  lines of numeric input:

The first line has a double, mealCost(the cost of the meal before tax and tip).

The second line has an integer, tippercent(the percentage of  being added as tip).

The third line has an integer,  taxPrcent(the percentage of  being added as tax).

Output Format

Print the total meal cost, where totalcost  is the rounded integer result of the entire bill ( with added tax and tip).

 In Cpp




#include <bits/stdc++.h>




using namespace std;




// Complete the solve function below.

void solve(double meal_cost, int tip_percent, int tax_percent) {

    float tip=(meal_cost*tip_percent/100);

    float tax=(meal_cost*tax_percent/100);

    float totalcost=meal_cost+tip+tax;

    cout<<round(totalcost);

}




int main()

{

    double meal_cost;

    cin >> meal_cost;

    cin.ignore(numeric_limits<streamsize>::max(), '\n');




    int tip_percent;

    cin >> tip_percent;

    cin.ignore(numeric_limits<streamsize>::max(), '\n');




    int tax_percent;

    cin >> tax_percent;

    cin.ignore(numeric_limits<streamsize>::max(), '\n');




    solve(meal_cost, tip_percent, tax_percent);




    return 0;
