Given a Scenario where i need to calculate the loss percentage in weight where the issued weight is in kg and grams and the received weight is also in kg and grams. so the scenario becomes 4 text boxes and a button and an extra text box to display the loss percentage. Can anyone please help me with this? Also the grams need to be converted into kg. I have tried it but whenever the grams is 000,it throws an error.

Where is your code? Where you are getting error? Look, this is just a homework and we are not having your HDD so that we'll solve your problem. While posting your question try to post the dummy codes also.

I transported myself to your place using tele-portation and checked your code. It seems there is issue in the code which needs to be fixed. After that it will not throw the error..

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

But your specific problem is simple:
"whenever the grams is 000,it throws an error."It will - division by zero generates a result that can't be stroed in a computer, so it generates a "devision by zero" exception. So check first:
```double kilos = 0.0;
if (grams != 0)
{
kilos = grams / 1000;
}```

Hey man, where is the division BY zero? :-D

I'm just guessing he doesn't know how divide works either! :O

(Phew, I think I got away with that...)

You need to convert the pairs `{kg,g}` into total `g` (simpler than converting to total `kg`) and then apply the percent formula (e.g. `100 * (issued-received) / issued`), being sure that divisor is greater than zero (as it, in any case but wrong input, should be).
