short s = 5; s = s - 2;
error: incompatible types: possible lossy conversion from int to short s = s - 2; ^ 1 error
// why below line ok ? ask java compiler. s -= 2; s = (short)(s - 2);
Java report error while c/c++ do not even display a warning message
in fact, c++ do the same things like Java do:
Automatic promotion of shot to int, but implicit the conversion.
