Is Not Null C at Hannah Broadwater blog

Is Not Null C. The null pointer is the pointer that does not point to any location but null. This is useful when you want to assign the result to a variable `if (getvalue() is { } value)`. Attempting to dereference a null pointer results in undefined behavior, and will usually lead to a runtime error, so you want to make sure a. If you are writing code that you don't want to depend on someone's implementation of the != and == operators, use is null and is not null because it is safer. (but `is not null value` does not compile). In c null can be defined as 0 or as ((void *)0), c99 allows for implementation defined null pointer constants. In c# 9.0 you can also test for not null with an empty property pattern. “an integer constant expression with the value 0, or such an expression. } beginning with c# 11, you can use list patterns to match. This syntax supports static analysis such that later code will know whether variable is null or not. If (result is not null) { console.writeline(result.tostring()); If (variable is { }) return false.
