unary increment operator i++ in C#

Question

In my last interview i found this tricky question. after these two lines what will be the value of i.

int i=c;
//c is a constant
i=i++;

where c is a constant(where c is initialised before). please give me step by step answer rather than one word answer.

Did you even bother to try to run the code? The question is addressed by section 7.6.9 of the C# 5.0 specification, but if all you want to know is what the code will do, it's silly to post a question here. You can just run it yourself. — Peter Duniho, Feb 14 '15 at 06:17

You need a better explanation than already exists in the duplicate question? — Peter Duniho, Feb 14 '15 at 06:28

finally value of i remains same as c.

Explanation:- when i is assigned with i++;

step 1. first i++ return value c(but not assigned to left-hand operand i).

step 2. then i++ increments value of i to c+1.

step 3. i is assigned with value c that is returned in step1.

In effect value of i remains same but some where along the execution it was c+1, But finally it is assigned with value c.
