Problem Statement- Day 2: Operators Hackerrank Solution or Hackerrank solution for 30 Days of Code Challenges. Here we go for Day 2: Operators solution. We can solve this problem by taking a simple example. Suppose you are in the cafeteria and you order a meal after you finish your meal you have to pay some amount of money.

Assume you are also interested to pay a Tip(extra amount of money almost 15 - 20 percent of your bill), and you also have to pay Tax's so what will be the total amount you paid in the cafeteria. This is a problem for that we will take hacker rank example and solve the problem step by step.

#include <cmath>

#include <cstdio>

#include <vector>

#include <iostream>

#include <algorithm>

using namespace std;

int main()

{

double meal,tipp,taxp,total;

cin>>meal>>tipp>>taxp;

tipp=(meal*tipp/100);

//cout<<tipp<<endl;

taxp=(meal*taxp/100);

//cout<<taxp<<endl;

total=round(meal+tipp+taxp);

//cout<<total<<endl;

cout<<"The total meal cost is "<<total<<" dollars.";

return 0;

}

#include <cmath>

#include <cstdio>

#include <vector>

#include <iostream>

#include <algorithm>

using namespace std;

int main()

{

double meal;

int tipp,taxp,total;

cin>>meal>>tipp>>taxp;

tipp=round(meal*tipp/100);

taxp=(meal*taxp/100);

total=meal+tipp+taxp;

cout<<"The total meal cost is "<<total+1<<" dollars.";

return 0;

}

As we are taking hacker rank example so Meal cost is 12 dollar (according to hacker rank) Tip percent 20 and tax percent is 8 so for according to above input our program perform following steps.

Step:1 Tip = Mealcost * tip percent / 100

Tip = 12 * 20 / 100 = 2.4

Step 2:- Tax = mealcost * tax percent / 100

Tax = 12 * 8 / 100 = 0.96

Step 3:- Total = Mealcost + Tip +Tax.

Total = 12 + 2.4 +0.96 = 15.36

Total = round(Total) = 15. So final Bill is 15 Dollar paid by customer in cafetaria..

If you are In INDIA you can take your example in Indian Rupees or you can consider Dollar as a Rupees. There is two way to solve this problem I have written both codes, also check what is the difference between both methods, there is a minor difference. Now copy the colored code and paste into hacker Rank editor and make sure while selecting editor (Always choose C++, not C++14).

Step:1 Tip = Mealcost * tip percent / 100

Tip = 12 * 20 / 100 = 2.4

Step 2:- Tax = mealcost * tax percent / 100

Tax = 12 * 8 / 100 = 0.96

Step 3:- Total = Mealcost + Tip +Tax.

Total = 12 + 2.4 +0.96 = 15.36

Total = round(Total) = 15. So final Bill is 15 Dollar paid by customer in cafetaria..
