Quick introduction to reverse engineering for beginners

1.16 C++ classes
I placed a C++ classes description here intentionally after structures description, because internally, C++
classes representation is almost the same as structures representation.
Let’s try an example with two variables, couple of constructors and one method:
#include
class c
{
private:
int v1;
int v2;
public:
c() // ctor
{
v1=667;
v2=999;
};
};
c(int a, int b) // ctor
{
v1=a;
v2=b;
};
void dump()
{
printf ("%d; %d\n", v1, v2);
};
int main()
{
class c c1;
class c c2(5,6);
};
c1.dump();
c2.dump();
return 0;
Here is how main() function looks like translated into assembler:
_c2$ = -16 ; size = 8
_c1$ = -8 ; size = 8
_main PROC
push ebp
mov ebp, esp
sub esp, 16 ; 00000010H
lea ecx, DWORD PTR _c1$[ebp]
call ??0c@@QAE@XZ ; c::c
push 6
push 5
