Post increment - perform operation first , then increment
In function call _l_abc its post increment, so after value 10 to be returned is decided , local variable i is increment , its i in function.
Variable i in _l_abc is different than i in main.
Post decrement : decrement first then perform operation.
In main its pre decrement , returned 10 is decremented to 9, then printed.
Now , unless compiler does not throw error of beginning function name with _ , 9 is printed.
