Monday's fascinating C# quiz

[eek]

I think the fact you didn't explains rather more.

It's thanks to the degree I did do, that I know how much of a cretin you really are.

Quiz Part II

If

static Func<int> Wibble()
{
int myValue = 0;
return () => myValue++; 
}
static void Main()
{
Func<int> wibble= Wibble();
Console.WriteLine (wibble()); // Prints 0
Console.WriteLine (wibble()); // Prints 1
}

What does

static Func<int> Wibble()
{
return() => { int myValue= 0; return myValue++; };
}
static void Main()
{
Func<int> wibble= Wibble();
Console.WriteLine (wibble()); // Prints?
Console.WriteLine (wibble()); // Prints?

print?

You're stupid enough to think a degree you did helps you understand people?
You'd better hope that little business you've got succeeds, because there's no way you're getting to the top otherwise.


Feck me what has the country done to its education system, that it churns out such imbeciles ?

Nope.

You clearly don't undertand closures and capturing.

Nope.

You clearly don't undertand closures and capturing.

Yep, that's fair. I'm baffled by Lambda expressions as well.

[suityou01]

On reflection, the method takes no arguments, and declares the variable each time setting it to zero so your first example looks wrong to me as how can it ever return anything other than 1?

Just sayin like.

That's tomorrow's fascinating C# quiz topic.

PS. It's also clear you don't know the difference between ++X and X++

Make for incomprehensible code by the looks of it
