Hello All!
I was just wondering if C++ classes could internally be represented in the following way:
#include <stdio.h>
struct A {
int a;
void (*ptr) (A *);
};
void display(A *ptr)
{
ptr->a = 2;
printf("ptr->a = %d", ptr->a);
}
int main()
{
A obj;
obj.ptr = display;
obj.ptr(&obj);
return 0;
}
The C++ equivalent could be something like:
#include <stdio.h>
class A {
public:
int a;
void display();
};
void A::display()
{
this->a = 2;
printf("a = %d", this->a);
}
int main()
{
A obj;
obj.display();
return 0;
}
So, do C++ compilers could actually convert C++ code to valid C code(something like the above example)? Or how exactly is it done(if done in any other way). This was just a simple class example. I couldn't think how access specifiers could be implemented in C. Any inputs would be helpful. I was just curious if the compilers actually did it this way.
Thanks a lot!
