translating oo features to C

[dvanguard]

I was wondering if there are any open source compilers out there to
translate the C++/Java/C#-like object model to C. Thanks,

David

An early C++ "compiler" perhaps?

As I understand it, C++ was initially precompiled to C source.

'cfront' might be what you're looking for, although I guess the generatted
code would be pretty illegibel to humans.

yep cfront did it (the original compiler for AT&T). I think comeau c++
compiler still does that: from C++ sources it generates C code

Here you go:

Don't imagine that reading the C output will be enjoyable.

Hidden pointers is what OO is all about for the most part.

The following in C++:


class Circle {
public:

double radius;

virtual double GetArea(void)
{
3.14 * radius * radius;
}

};



is implemented as:



typedef struct VTable_Circle {
double (*GetArea)(Circle*);
} VTable_Circle;

typedef struct Circle {
VTable_Circle const *vtable;

double radius;
} Circle;

double GetArea(Circle *const this)
{
return 3.14 * this->radius * this->radius;
}

VTable_Circle vtable_circle = { GetArea };

void ConstructCircle(Circle *const p)
{
p->vtable = vtable_circle;
}
