WriteLine contain Null value.
The null comparison here null is a null reminder that were talking about a pointer.
Either standardize or dont.Using System; using neric; using nq; using System.Personally I could go null either way, but typically I skip the explicit comparison (though some people dislike this which is probably why you checking have null a contributor checking suggesting a change anyway).It contains the data checking stored in the nullable type.C# 6 has a neat shorthand checking solution for that, here you are: if!
For example, the library function malloc will return a crack null pointer value if it cannot allocate the number of bytes that have acoustics been requested, and attempting to access memory through that pointer will (usually) lead to a runtime error: int *p malloc(sizeof *p *.
I have a preference for code that says what it means without unneeded text.
I always use the following: if (ptr) if (!ptr) even on integers or other type that converts to bool: while(i-) / Something to do i times while(cin a b) / Do something while you've input Coding in this style is more readable and clearer.
Nullptr manual Until you are able to migrate to C0x I would argue its a waste of time worrying about which of these methods you use, they are all insufficient which is why nullptr was invented (along with generic programming issues which came up with perfect.
By default, all reference types, raider such as ilok strings, are nullable, but all value types, such as Int32, are not.Do not assume that the null pointer value is always.As per the msdn definition: The? .Also I feel the second method has a smaller chance of introducing a bug of the ilk: which is just with an absolute pain to find and debug.C is a different beast.The null pointer constant, otoh, is always a 0-valued integral expression.Seriously, service without a style guide I would push to NOT change code like this as a matter of principle, even when it doesnt use the convention I prefer.There are two members of a nullable type.Dont let a reviewer pseudo-standardize just because hes got an opinion.A value type variable cannot be null, but we can assign a null value in the reference type variable.
