# Hackerrank Day 2 Operators 30 days of code solution

In this HackerRank Day 2 Operators 30 days of code problem there is Given the meal price (base cost of a meal), tip percent (the percentage of the meal price being added as a 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. Round the result to the nearest integer.

## Problem solution in Python 2 programming.

```# Enter your code here. Read input from STDIN. Print output to STDOUT
price = float(raw_input().strip())
tip = int(raw_input().strip())
tax = int(raw_input().strip())
print "The total meal cost is %i dollars." % int(round(price*(100+tip+tax)/100))```

## Problem solution in Python 3 programming.

```#!/bin/python3

import math
import os
import random
import re
import sys

# Complete the solve function below.
def solve(meal_cost, tip_percent, tax_percent):
tip = meal_cost * tip_percent / 100
tax = meal_cost * tax_percent / 100
total_cost = meal_cost + tip + tax

print(round(total_cost))

if __name__ == '__main__':
meal_cost = float(input())

tip_percent = int(input())

tax_percent = int(input())

solve(meal_cost, tip_percent, tax_percent)```

### Problem solution in java programming.

```import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;
public class Arithmetic {

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

double tip = mealCost * tipPercent / 100;
double tax = mealCost * taxPercent / 100;
double total = mealCost + tip + tax;

// cast the result of the rounding operation to an int and save it as totalCost
int totalCost = (int) Math.round(total);

System.out.println("The total meal cost is " + totalCost + " dollars.");
}
}```

### Problem solution in c++ programming.

```#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;

int main() {
/* Enter your code here. Read input from STDIN. Print output to STDOUT */
double mealCost;
double totalCost;
int totalCostRound;
int tipPercent;
int taxPercent;

cin >> mealCost >> tipPercent >> taxPercent;
totalCost = mealCost * (1.0 + (double)taxPercent/100.0 + (double)tipPercent/100.0);
totalCostRound = (int)(totalCost + 0.5);
//    cout << mealCost << ", " << tipPercent << ", " << taxPercent << endl;
cout << "The total meal cost is " << totalCostRound << " dollars.";
return 0;
}```

### Problem solution in c programming.

```#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>

int main() {

/* Enter your code here. Read input from STDIN. Print output to STDOUT */
float mealValue;
int tip;
int tax;
unsigned int total;
/* Enter your code here. Read input from STDIN. Print output to STDOUT */
scanf("%f",(float *)&mealValue);
scanf("%d",&tip);
scanf("%d",&tax);

total = mealValue + (mealValue*((float)tip/100)) + (mealValue*((float)tax/100)) + .5;
printf("The total meal cost is %d dollars.", (int)total);
return 0;
}```

### Problem solution in Javascript programming.

```function processData(input) {
var pieces = input.split('\n');
var mealCost = parseFloat(pieces[0]);
var tipPercent = parseInt(pieces[1]);
var taxPercent = parseInt(pieces[2]);

var total = mealCost * tipPercent / 100 + mealCost * taxPercent / 100 + mealCost;

console.log('The total meal cost is ' + Math.round(total) + ' dollars.')
}

process.stdin.resume();
process.stdin.setEncoding("ascii");
_input = "";
process.stdin.on("data", function (input) {
_input += input;
});

process.stdin.on("end", function () {
processData(_input);
});```
