Answer 2

The following is the actual question:
What is the output of the following code?
int a=3;
int b=2;
b=a++;
cout<<++b;

Answer 3

I found it, it is the last module quiz question of basic concepts in C++

However it says
b = a++
in the second last line.

This makes answer 4 correct, since b is assigned 3 if we use a++ instead of ++a

Answer 4

I didn't understand this completely. Is this problem somewhere in C++ lessons or does it happen when you run the code? The output indeed should be 5.
