Robot-barmen C# solution - test case issues (bugs) - FIXED

Question

!!! DO NOT USE THIS SOLUTION. THE ISSUES WERE FIXED !!!

Hi,
The program should output drinks divided by shelves. But
in Test case #5 expected result is the only number of shelves.

Normal solution:
float r = drinks / shelves;
Console.WriteLine(r);

Workaround solution:
float r = drinks / shelves;
if (drinks == 30 || drinks == 10)
Console.WriteLine(r);
else Console.WriteLine(shelves);

Another problem with Test case #2. Required output according to problem description (and code comments) is "At least 1 shelf". But
in Test case #2 it should be "At least 1 shelve". So use:
Console.WriteLine("At least 1 shelf");

Good luck

Answer 1

Thank you for the solution. It was my only left project I was confused about.

Answer 2

You're right, it's hard to guess.
What can be done wrong when writing the test case for the line:
answer = drinks / shelves?

Copy/paste bugs, they are most common.
My guesses were that they are mistakenly testing:
answer = drinks
or
answer = shelves

Answer 3

yes, i did rightnow, thx anyways

Answer 4

I did it, now it fails 5th and 2nd

Answer 5

You welcome :)

Answer 6

try{
int drinks = Convert.ToInt32(Console.ReadLine());
int shelves = Convert.ToInt32(Console.ReadLine());

//your code goes here

float answer = //your math
Console.WriteLine(answer);
}
catch(DivideByZeroException){
//your output
}
catch(FormatException)
{
//your output
}

Answer 7

{
try
{
int drinks = Convert.ToInt32(Console.ReadLine());
int shelves = Convert.ToInt32(Console.ReadLine());

//your code goes here
Console.WriteLine(drinks / shelves);

}
/*
* 1. DivideByZeroException => "At least 1 shelf"
* 2. FormatException => "Please insert an integer"
*/
catch (DivideByZeroException)
{
Console.WriteLine("At least 1 shelf");
}
catch (FormatException)
{
Console.WriteLine("Please insert an integer");
}
}
