+ AnswerC

+ ExplanationTurbo C++ 3.0: 8
Turbo C ++4.5: 8
Linux GCC: 16
Visual C++: 16

Default data type of signed, unsigned, const and volatile is int. In turbo c 3.0 size of int is two byte.
So, a = 4 and b =4
Now, a+++b
= a++ + b
= 4 + 4  //due to post increment operator.
=8
Note: In turbo c 4.5 and Linux gcc compiler size of int is 4 byte so your out will be 16
