any method to view the trick of compiler?

[thomas]

class A{
public:
int x;
};
class B{
public:
A a;
int y;
};

in the above code, the comiler is expected to synthesize a default
constructor for A.

Is there any method to view the extra code the compiler generates?

The compiler doesn't generate source code, it generates machine code.
Your options would be to look at the resulting code in the debugger,
or request an assembly language listing (if available).

Given that x is not initialized at all, I don't think the compiler is
forced to generate any code at all as the "constructor" of A.
