- Difference between pre-increment and post-increment in a loop?
In other languages such as C# where the ++ operator can't be overloaded there is no performance difference Used in a loop to advance the loop variable, the pre and post increment operators are equivalent Correction: overloading ++ in C# is allowed It seems though, that compared to C++, in C# you cannot overload the pre and post versions independently So, I would assume that if the result
