Problem in code coach

Question

https://www.sololearn.com/coach/22?ref=app

Why don't solve all cases? (copy-paste)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
uint pintures = Convert.ToUInt32( Console.ReadLine() );

if ( pintures > 0) {

uint subtotal = pintures * 5 + 40;

float tax = subtotal * 10 / 100;

uint total = subtotal + Convert.ToUInt32( Math.Round( tax ) );

Console.WriteLine( total );
}

else if ( pintures == 0)
Console.WriteLine( 0 );

}
}
}

Answer 1

Kiwwi I've just noticed that those if statements in the code are doing nothing much.

A much cleaner version of your code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
var pintures = Convert.ToInt32(Console.ReadLine());

var subtotal = pintures * 5 + 40.0;
var tax = subtotal * 10 / 100;
var total = subtotal + tax;

Console.Write(((total-(int)(total))>=0.5f) ? Math.Ceiling(total) : Math.Floor(total));

}
}
}

Kiwwi

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
var pintures = Convert.ToInt32(Console.ReadLine());

if ( pintures > 0) {

var subtotal = pintures * 5 + 40.0;
var tax = subtotal * 10 / 100;
var total = subtotal + tax;

Console.Write(((total-(int)(total))>=0.5f) ? Math.Ceiling(total) : Math.Floor(total));
}

else if ( pintures == 0)
Console.WriteLine( 0 );

}
}
}

Answer 3

Are you having problems with that problem, if yes then pls post your question so that we can figure it out

Answer 4

hey Kiwwi the problem is with the rounding.

Answer 5

(geeksforgeeks) ceil & floor

Answer 6

You declared uint for pintures variable, so pintures always >= 0.
If pintures <0, your programming will error.

Answer 7

Don't solve all evaluation cases, but think its the correct solution, so I put it here to others can check (copy-paste on the link to review it)

Answer 8

Nguyễn Văn Sơn yes, but before did with normal int and the same problem

Answer 9

Yes I see that now, but don't know ceiling and floor yet, what they do?
