If i == 0, why is (i += i++) == 0 in C#?

//source code i += i++; //abstract syntax tree += / \ ii (post) \ ++

// source code i += i++; //abstract syntax tree += / \ i ++ (post) \ i First, i++ returns 0. Then i is incremented by 1. Lastly i is set to the initial value of i which is 0 plus the value i++ returned, which is zero too. 0 + 0 = 0.

inti = 0; i = i + i; i + 1;

int ++(ref inti) { int c = i; i = i + i; return c;}

Answer

Correct Answer: inti = 0; i = i + i; i + 1;
