Java: Different output than given in the result

[Hip]

Hey guys,

 

I have the following code that I have given in a task sheet but in the results the output and the explanation of it is different than what the code outputs.

public class Main
{
	//create mainmethode
	public static void main(String[] args)
	{
		//declare Variables
		int d1, d2, help, count;
		
		//initialize Variables
		d1 = 23;
		d2 = 5;
		help = 0;
		count = 0;
		
		help = d1;
		
		while(help >= d1)
		{
			help = help - d2;
			count++;
		}
		
		//Output
		System.out.println(d1 + " " + d2 + " " + count + " " + help);	
	}
}

So the output is 

Quote

23 5 1 18

But the result should be (taking from the result of the task sheet)

Quote

23 5 4 3

...because, the program is dividing 23 with 5 and the output is the first number + number that it divides with + multiplier + rest.

 

At least this should be the output, but I copied the code 1:1 and when I go through the while loop I don't get the result.

Can you please explain me what is wrong?

 

Thanks in advance.

Nowhere in your program are you doing any division.

 

The only variable you change is help, which you are subtracting d2 (5) from help (23), resulting in help equaling 18. Because 18 is less than 23, the loop only iterates once and exits, resulting in help equaling 18 and count only equaling 1.

Exactly! That's why I wonder where the Professor that created this task is taking his results from!

I am really confused by this.

 

Thanks for the fast reply.

I think this loop is MEANT to be division. some minor tweaks and:

//declare Variables
int dividend, divisor, remainder, quotient;

//initialize Variables
dividend = 23;
divisor = 5;
remainder = 0;
quotient = 0;

remainder = dividend;

while (remainder >= divisor)
{
  remainder = remainder - divisor;
  quotient++;
}

//Output
System.out.println(dividend + " " + divisor + " " + quotient + " " + remainder);

 

So perhaps the professor just had the conditional wrong in the while loop, and it should actually be help >= d2 instead of help >= d1? I don't see what the original could be trying to accomplish, since it would always terminate after only 1 loop assuming only positive numbers.

You could be right here, thanks for the reply.
