Hi im not sure that my code is working as it should(class in c sharp)

providing code here👇(When i add +1 or +10 to the GetX or GetY isn't it supossed to change?)

$details

MODiX•2y ago

When you ask a question, make sure you include as much detail as possible. Such as code, the issue you are facing, and what you expect the result to be. Upload code here https://paste.mod.gg/ (see $code for more information on how to paste your code)

avishyOP•2y ago

i did

Buddy•2y ago

Actually, it doesn't mention title. But either way, please name your title well, instead of naming it like it doesn't work and I don't know why $code

MODiX•2y ago

To post C# code type the following: ```cs // code here ``` Get an example by typing $codegif in chat If your code is too long, post it to: https://paste.mod.gg/

avishyOP•2y ago

i wrote the code

Buddy•2y ago

You failed the highlighting

avishyOP•2y ago

i dont know how else to name it

Buddy•2y ago

make sure you write a new line when you write cs

@Buddy delete ur msgs so ppl wonth ave to serch for the code

Buddy•2y ago

What is SetX? and SetY

avishyOP•2y ago

its up on the code

Buddy•2y ago

and the other functions It is not, you have not posted that.

you can use this website if it's too long $paste

MODiX•2y ago

If your code is too long, you can post to https://paste.mod.gg/ and copy the link into chat for others to see your shared code!

avishyOP•2y ago

its ok it works but ty but i need help with my question

Buddy•2y ago

You are not printing the variables that you have set

avishyOP•2y ago

ToString is returning them

Buddy•2y ago

            double point1X = (point1.GetX() + 1);
            double point1Y = (point1.GetY() + 1);
            double point2X = (point2.GetX() + 10);
            double point2Y = (point2.GetY() + 10);

            double point1X = (point1.GetX() + 1);
            double point1Y = (point1.GetY() + 1);
            double point2X = (point2.GetX() + 10);
            double point2Y = (point2.GetY() + 10);

You must use the newly declared variables it does not set the values of point1, point2

avishyOP•2y ago

how can i change them then without changing the set i mean

Buddy•2y ago

You can't, unless you add that to your Point class or make x / y public

avishyOP•2y ago

so i cant change it in main without changing the set?

Buddy•2y ago

GetX / GetY returns a copy of x, it is not the reference of x. $refvsvalue

MODiX•2y ago

avishyOP•2y ago

but then i add to it the +1 it doesnt affect the actual point?

Buddy•2y ago

So based on your current code, the only way to add to X is:

point1.SetX(point1.GetX() + 1);

point1.SetX(point1.GetX() + 1);

avishyOP•2y ago

ohh okay ty how do i call PrintDistance in main?

Buddy•2y ago

Point.PrintDistance as it is a static method $static

MODiX•2y ago

In C#, static allows you to have members (classes, methods, etc) that are not tied to any particular instance and are therefore always, globally, accessible. When applying static members, take the following considerations: • If there are to be multiple instances of a class, do not use static • If you need to track state, do not use static • If you are going to have multi threaded workflows, do not use static unless you're aware of the caveats static is best used for stateless methods, extension methods/classes and in areas where you understand the pros/cons. Read more here: https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/static

avishyOP•2y ago

thank you but if i try that with IsEqualTrinagnle it doesn't work, is it not a static method? does bool count as static?

Buddy•2y ago

static keyword count as static
