This answer is what??

Question

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)
{

int x = 1;
while(x++ < 5)
{
if (x%2==0)
{
x+=2;
}
}
Console.WriteLine(x);
}
}
}
output 6
but answer question this level is number 2
what???

Answer 1

so, x start as 1. is x%2 ==0? nope, so next loop.
x its 2 now. its x%2 == 0? yes, so x+=2 .
x its 4 now. Its 4%2==0? yes, so x+=2.
x is 6, end of while, print x.

Answer 2

read the question again. The output of x is not the solution ;)

Answer 3

I don't think I fully understand how 6 is the answer. Nor will I be the last person to read and question this.
So for clarification purposes(?).

I get how 'x+=2' is simply;
take 'x' and add '2', then reassigning 'x' as the new value.

The '%' means Module, but what is 'x' being divided by?
Is the question referring to x / 2 with a remainder of exactly equal to 0?

- Thankx in advance.

Answer 4

this answer in this emulator and visual studio and trace in paper is 6
why answer in question in app is 2?

Answer 5

this is code this app

Answer 6

only 2 and 4 would have no remainder if divided by 2 satisfying the %2==0 statement. therefore the answer is two outputs.

Answer 7

Bruce-Michael Draper Yes, it evaluate the remainder of division. Generally, the module '%' returns remainder of division.
For ex.:
You know that 5/2=2 ('/' returns integer value and drop the remainder), so:
5%2=5-((5/2)*2)
Generally: x%y=x-((x/y)*y) where y != 0
