What is the n variable (C# Puzzle)?

You shouldn't use an IDE for an answer. Use your brain. var n = 2; n = n+++ ++n; // n = ? P.S. For any .net framework and any C# versions compiler behavior will be the same.

1 Answer
+ 2
6 Explanation: We declared that n is equal to 2, the next line shall be separated to 4 parts. n = n+++ ++n; n+++ is simply n++ and another + of addition between n++ and ++n. The n++ tells us that n will increase after the entire line is executed. ++n tells us to increase the value of n by 1 right now. So n = n++ (n stays the same) + ++n (n increased by 1, only this n though) is analogical to n = 2 + 3; n = n + 1; (is the n++ in the previous line) Therefore the answer is 6.
