Please explain the output

Question

int a= 30;
int b=6;
cout << a/b--;

Answer 1

B decrements to 5 after the statement has finished,if you print the result 2 times you will see this.

Answer 2

Thirteen post decrement operator is used here(not pre-decrement) so the value of *b* will be decremented after the calculation of "a/b" thus the answer should be 5 instead of 6.
