public class Arithmetic

    Scanner scan = new Scanner(System.in); 
    double mealCost = scan.nextDouble(); // original meal price 
    double tipPercent = scan.nextDouble(); // tip percentage 
    double taxPercent = scan.nextDouble(); // tax percentage 
    scan.close(); 

    // Write your calculation code here. 
    tipPercent = mealCost*tipPercent/100.0; 
    taxPercent =mealCost*taxPercent/100.0; 



    //cast the result of the rounding operation to an int and save it as totalCost 

    double totalCost = mealCost + tipPercent + taxPercent; 

    // Print your result 
    int total = (int)totalCost; 
    System.out.println("The total meal cost is " + total + " dollars."); 
} 
} 

entrée:

Résultats escomptés: Le coût total du repas est de 23 dollars. Résultat: Le coût total du repas est de 26 dollars.

Quel est le problème avec ce programme?

Answer 1

Vous n'utilisez pas votre pourboire et vos taxes.

Il devrait être:

tipPercent = mealCost*tipPercent/100.0; 
taxPercent = mealCost*taxPercent/100.0; 

Answer 2

enfin ce code fonctionne parfaitement

import java.util.*; 
import java.math.*; 

public class Arithmetic 
{ 

public static void main(String[] args) 
{ 
    Scanner scan = new Scanner(System.in); 
    double mealCost = scan.nextDouble(); // original meal price 
    double tipPercent = scan.nextDouble(); // tip percentage 
    double taxPercent = scan.nextDouble(); // tax percentage 
    scan.close(); 

    // Write your calculation code here. 
    tipPercent = mealCost*tipPercent/100.0; 
    taxPercent =mealCost*taxPercent/100.0; 

    // cast the result of the rounding operation to an int and save it as 
//totalCost 
    double totalCost = mealCost + tipPercent + taxPercent; 

    if((tipPercent + 0.5)>=((int)tipPercent + 1)) 
     { 
      totalCost += 1; 
     } 
     else 
    { 
    } 
    // Print your result 
    int total = (int)totalCost; 
    System.out.println("The total meal cost is " + total + " dollars."); 
} 
}
