CSharp Help please!

Directions:
Fill in the blanks to instantiate an object of the class Cat, passing to the constructor the value 12. Then call Meow method for that object.

Cat c = ___ Cat(__);
__Meow();

Can someone help me fill in the blanks?

var cat = new Cat(0xc);
cat.Meow();

Complete variable names are always good practice.

Re: CSharp Help please!

If you're using cat once.

(new Cat(12)).Meow();

---

while(true)
   cat.Meow();

hehehe

while (true) {
    Thread.Sleep(100);
    _connection.Send("say", "/kick gosha Meow")
    Thread.Sleep(100);
    _connection.Send("say", "/forgive gosha")
}

I learn fast

Random rng = new Random();
while(true) {
    con.Send("say", "/teleport AnatolyEE {0} {1}".MelodyFormat(rng.Next(0,worldX),rng.Next(0,worldY))); // I'm too poor to use C# 6 so I just did this stupid Extension Method
    await Task.Delay(20);
}

Complete variable names are always good practice.

For things where the return type is explicit (like when instantiating) I actually generally see the use of var being used since... As I said: it's explicit, obvious.

Myself I still prefer explicit variable type declaration. When I'm not sure what type the variable was, I look at the declaration, not where it's value is actually set (since generally that's in a ton of places that don't have any obvious position), meaning that if I'd put var there, I'd still have to keep looking around.
That's also why I dislike JavaScript to a degree, since I like to know and control exactly what type the variable is from the very start.

not worrying about type declaration is why I love lua.

Directions
Fill in the blanks to overload the minus operator for the T class:

public ___ T ____ - (T a, T b)
{
  T res = new T(a.num - b.num); 
  ____res;
}

There's another.

Also what is "0xc?"

var cat = new Cat(0xc);
cat.Meow();

Re: CSharp Help please!

0xc is a hex value

Decimal numbers are
0 1 2 3 4 5 6 7 8 9

Hex values are
0 1 2 3 4 5 6 7 8 9 a(10) b(11) c(12) d(13) e(14) f(15)

C is equal to 12 in decimal.
So 0xC means 12

this smells a lot like homework, are you sure you want to be asking?

Re: CSharp Help please!

I'd highly recommend figuring these things out yourself through actual practice, you won't learn very much by getting the answers handed to you.
In any event, having the answers directly provided to you is fine as long as you're acknowledging that memory alone won't help you very far in the long run.

public override T operator - (T a, T b)
{
  T res = new T(a.num - b.num); 
  return res;
}

or, if they accept less verbose examples,

public override T operator - (T first, T second)
{
  return new T(first.num - second.num);
}

also before anyone comments, this could be done but eh, it seems dodgy

public override T operator - (T first, T second) =>
  return new T(first.num - second.num);

Re: CSharp Help please!

Off topic:

public override T operator - (T first, T second) =>
  return new T(first.num - second.num);

Actually got a classmate that, once he discovered Linq and Lambda expressions, he tried to pump his code full of it.
He's the kind of dude that find something cool, throws away everything he's learned before, and tries to do everything with "this awesome thing I just discovered".

Terribly annoying...

the topic has essentially snuffed out but remember these sorts of discussions aren't EE-related so they go to Off-Topic

    await Task.Delay(20);
}

worldX and worldY is null, so it will return an error.

then set them to something
