Comment just above is "Fixed - they changed the initial code", so I'm pretty sure for now it works just fine :)

Thank you

I think using Math.round() would be much easier than using if statements.

Don't overthink it....

// Complete the solve function below.
function solve(meal_cost, tip_percent, tax_percent) {
    const tip = meal_cost * tip_percent / 100;
    const tax = meal_cost * tax_percent / 100;

    const total = Math.round(meal_cost + tip + tax)
    console.log(total);
}

Yes! Thank you!

Great thanks!!!!!, you saved my life!!!!

Thanks!

This did it for me! Thanks buddy

Can you explain your logic

I get a TypeError when I run the code in Jupyter Notebook. Can you please explain?

TypeError Traceback (most recent call last) in ----> 1 print(round(float(input() * (1 + int(input()) * 0.1 + int(input())* 0.1))))

TypeError: can't multiply sequence by non-int of type 'float'

Thank You.

I had the same confusion and still not very clear. Can u help me understand it.

Thank you.

Good Explanation. Thank you for sharing your knowledge.

i used 100.0 but still failed the 4th test case. what am i missing ?

Thank You

Thanks alot Allison

i face this same problem so i multliply tippercent with mealCost then devide by 100 answer is right but test case not accepted what should i do?

Thank you!

The below code is also giving as wrong answer but we are curious to know why it is wrong .. can any one help us in knowing that ...

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();

    // Write your calculation code here.
    double tip= (mealCost*(tipPercent))/100.0;
//    System.out.println("tip is"+tip);
    double tax= (mealCost*(taxPercent))/100.0;

// System.out.println("tax is"+tax); mealCost=mealCost+tip+tax;

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

    System.out.println("totalcost"+totalCost);
    // Print your result
}

Thank u

Thank You!

but could I cast it first and then * mealCoast ?

thank you.

Thank you

Clear Clarification of Basics :).

Thank You!

Its not PEMDAS.. it is BODMAS rule which tells us the order of performing arithematic operations when there are more than one operations, i.e Bracket,Of,Division,multiplication,addition,subtraction.This is decreasing order of priority for performing different arithmatic operations.

Thank You Allison.

Thanks a lot

my program runs and gives the correct output but it's said to be incorrect. i do not know what i am doing wrong,any suggestions?Thank you in advance

/* Enter your code here. Read input from STDIN. Print output to STDOUT */
double mealCost; int tipPercent, taxPercent; double tip, tax, totalCost;

cin>>mealCost>>tipPercent>>taxPercent;

//calculate tip and tax amounts
tip = mealCost * ((double)tipPercent/100);
tax = mealCost * ((double)taxPercent/100);

//calculate total meal price
totalCost = mealCost + tip + tax;
double cost = round(totalCost);

//display total meal price
cout<<"The total meal cost is "<<cost<<" dollars"<<endl;

return 0;

}

int main() { /* Enter your code here. Read input from STDIN. Print output to STDOUT */
double mealCost; int tipPercent; int taxPercent; cin>>mealCost; cin>>tipPercent; cin>>taxPercent; float tip,tax; double totalCost;

tip=(mealCost*tipPercent)/100;
tax=(mealCost*taxPercent)/100;
totalCost=mealCost+tip+tax;
totalCost=(int)totalCost;
cout<<"The total meal cost is "<<totalCost<<" dollars.";

return 0;

} please tell me what is wrong in this code ?

Thank you a lot. I did not notice that until I read your comment.

thank you :)

thnks!

true

but how to write a program?

I got the same problem but this does not solve my problem.

Thanks, I also encountered this!

thank you

Please can you help me on this, I cant seem to round my answer. I tried putting plus one the totalCost but I fail the last test case.

using System; using System.Collections.Generic; using System.IO; using System.Linq;

class Solution { public static void Main() { double mealCost; double tipPercent; double taxPercent;

    mealCost = Double.Parse(Console.ReadLine());
    tipPercent = Double.Parse(Console.ReadLine());
    taxPercent = Double.Parse(Console.ReadLine());

    int tip = (int) mealCost * (int) tipPercent / 100;
    double tax = (int) mealCost * (int) taxPercent / 100;
    double totalCost = (int) mealCost + tax + tip;

    Console.WriteLine("The total meal cost is {0} dollars.",totalCost);
    }
}

Thanks

Thanks! :)

Thank you so much.

I didn't get the '%' part here. How is the multiplication happening with 0?

I have added it as 100.0 bt still I'm facing it can u help me plz

thank u

you can also declare 100 as a double this way: mealCost*(tipPercent/(double)100)

Hoho!! Thanks for that!!

¡Gracias!

Thanks a lot for the explanation..

Thank you 2 times more than anyone else here :)

Thank You

*why my code is giving error plz tell it is matching with the required output main() { double mc; float tip,tax; int ttip,tp,totalcost; scanf("%lf%d%d",&mc,&ttip,&tp); tip = (mc((ttip)/100.0)); tax = (mc*((tp)/100.0)); totalcost =mc+tip+tax; printf("The total meal cost is %d dollars",totalcost); /* Enter your code here. Read input from STDIN. Print output to STDOUT / return 0; *

Some countries like in India we follow BODMAS which gives a different output.

Thank you)

Thank you so much I was so confused before.

Casting does not work!!

Thanks bro,

Thanks bro,

Thankyou AllisonP

works in the us, where order of operations is --MDAS, not so much anywhere else, where order of operations is --DMAS.

thank you...

I m still not getting the correct answer.its giving output as 12 dollars i.e. taking tip and tax as zero.Where is the problem please help?

What happened to good old BODMAS????

Thank you very much, this explains a lot too me, I spent more time trying to get this one than I should have because of this, I didn't think about two ints in parenthesis producing an int in the equation.

Thanks

Thank you!

thank you

thank u so much for your clear explaination

Thank you so much !

Cool

Thanks. Very helpful.

Thanks! This explains it perfectly!

thanks for this

Ahh, changing it to 100.0 fixed it, thank you! I never would have thought of that.

Thanks .. You taught me something new today.

hey can u explain why

int f=240; float t=(float)f/100; then t will be t=2.0

if float t=(float)f/100.0; then f=2.4;

Brilliant.

plz explain

thank you Vanshika_bhardw1, it worked.

I also has the same problem what to do???

OMG!! Thanks a lot Vanshika. Had the same problem, was banging my head as I had uploaded my code so many times. The period was the problem. Just happened to read this post.

hey what do you mean by period after 15 dollars .I am also facing the same problem can you suggest me

Thanks! I had this same issue and I could not find that period somehow until reading this comment. Then of course once I saw it I couldn't fathom why I didn't notice it before!

dont you think round() should be used on the final value we get, as shown in expalantion part of the problem also??? i have tried this and it is also passing all the test cases.So, your code will be soemthing like this: double mealCost, tip, tax; int tipPercent; int taxPercent; int totalCost;

cin >> mealCost; cin >> tipPercent; cin >> taxPercent;

tip = (mealCost * tipPercent/100); tax = (mealCost * taxPercent/100); totalCost = round(mealCost + tip + tax); cout << "The total meal cost is " << totalCost << " dollars.";

System.out.printIn where is the error in it always said there is a compile error ..symbol cannont found

It's like you are getting the input from the system itself. Check that you'll have 2 test cases to clear this testcase0 and testcase1. So which you give cin or scanf such that it defaultly checks both the testcase.

Thanks

thank you sweadon its very helpful..

Compile time error Compile Message File "solution.py", line 3 let mealCost: Double = Double(readLine()!)! ^ SyntaxError: invalid syntax-----This kind of error is showing..

thx man, it problem fully eat my brain) Ps:tested over 100 combinations, on cpp and no catch any working it possible, really?

This logic will not work for test case 3. Or any cases that returns total cost to be x.51 to x.55.

C rounds 0.5 down, so I guess C++ does, too. 10.25 with 17% tip and 5% tax would be 12.505 which would round to 13. If you're rounding the tax and the tip before adding them to the meal cost then you'd be getting 12.50 which would round to 12.

try this for round off::

int roundNo(float num)

{ return num < 0 ? num - 0.5 : num + 0.5; }

I also encountered wrong answer in the 3rd test case. Thus I tried below ways which actually works

int TotalCost = (int)round(totalCost);

Though I am checking if any smarter solution on it?
