Output and null

Feb 23rd, 2009

Hello. I have written the code below but when I compile my program, I get

Taxable Income Amount Filing Status Tax Amount
-------------------------------------------------------------------------------
$50,000.00 null $0.00

I initialized my String output as null but I do not know how to initialize it otherwise. And I need my output to be called back to the main method in order to compute taxfinal. Can someone please help?

Re: Output and null

you are passing by value, therefore any changes made to "output" are only made within the method.

{
  int var = 0;
  somemethod(var);
  print var;
}
 
somemethod(int var) {
  var = 5;
}
{
  int var = 0;
  somemethod(var);
  print var;
}

somemethod(int var) {
  var = 5;
}

this is just pseudo code. in this example, the output of the code (printing var) will NOT be 5, but 0. the value of var is passed to the method, and so the method can use this, but any modifications to var are only valid within the method, it doesn't change var of the caller.

So I think my next question is how do I get the value of output back to the caller method. Thanks.

You only need to return a single value from that method: the value the user selected from the menu.

you are returning the value, but doing nothing with it. another question, are you actually returning the correct value?

Well it seems that I am returning 'enter' so that should be stored in the calling method and I changed the second return to 'taxreturn'. So that should call enter from the calling method and return taxreturn up to the top and then should display it on the bottom. I think my logic is probably off.

what is the point in returning "enter" when all your logic related to "enter" is already complete within the method? and as i said previously, simply returning a value is useless unless you actually use it (e.g. assign it to something...).
