Why is a still 0 after that operation?

Question

Why is a still 0 after the following operation?

int a = 0;
a+=a++;

Google postfix and prefix increment operators.If you want 1 ,then do `a+=++a` — Spikatrix, Nov 09 '14 at 11:24

a++ increments a but returns its previous value 0.

That's why a+=a++, which is equivalent to a=a+a++, sets a back to 0+0;
