overloading operators in fpc?

[alsor]

Is it possible to define operators in the fpc, like in the c++?

for example:

object = xyz
x,y, z : double;

operator * (a,b)...

end;



then using something like this:
xyz a, b, c;

c = a + b ;

?

I take it you did not like C++?

I think it's not explicitly mentioned in the documentation, but only operators that don't have an existing built-in operation can be overload (so you can't overload e.g. Integer * Integer while Integer >< Integer (symmetric difference, not a mistyped <>) is fine).

no, i'm just total expert in the c++ programming.

inline operator + (int a, int b) { return a * b; }

can You rewrite this code to the free-pascal?

inline operator + (T3DPoint a, T3DPoint b) { return T3DPoint(a.x+a.x, a.y+b.y, a.z+b.z); }

Why would you bother with Pascal If you are an expert in C++?

inline operator + (T3DPoint a, T3DPoint b) { return T3DPoint(a.x+a.x, a.y+b.y, a.z+b.z); }

It is clear you didn't read the link to the relevant FPC documentation that Martin posted...

I have some very precious pascal coded application from very old version of Windows yet...
and now I try to recode it, but with the minimal cost of coding - direct recoding this code to c++ code would cost me a tremendous coding times.


And additionally: I begin with pascal long time ago, thus I'm an indisputable pascal expert too.
This is a primitive tool in fact, but I can still code everything using it.

No, you should not do it.

I don't know much about C++, I'm just a hobbyist that can use Pascal and BASIC to write some simple games. But I heard many people said proper written C++ code is faster than those in Pascal. Also a lot of programmers think Pascal now is dying.

Would you put your precious applications in Pascal? That clearly is a bad idea.

[lainz]

Too much noise for such a simple question (and I'm contributing to it).

[alsor]

I don't think... the programing language is illusion only: any code is applicable in any other language; the key is just a mastering of programing in general;
any coding language is the same in fact (with some exclusions of course).

[Handoko]

Interesting. You really said something that differs from what most people said. I'm starting to like you.

[engkin]

@Handoko, don't get deceived, "talk is cheap," ask him to show you the code. He is expert in this and expert in that. And no, languages are not equal. Some languages would help you shoot yourself in the foot, every day.


"very precious pascal coded application"
Pure B.S. but entertaining

inline operator + (int a, int b) { return a * b; }

Note PascalDragon's point from earlier: you can't redefine operators on basic types.

Also you can only redefine operators which already exist, and even that excludes things like ^

can You rewrite this code to the free-pascal?

inline operator + (T3DPoint a, T3DPoint b) { return T3DPoint(a.x+a.x, a.y+b.y, a.z+b.z); }

Yes. Read the links you've been given.

And pleasingly modest to boot :-/

FPC has various modes to tune it to Delphi etc. But I'm sure you knew that from your perusal of the documentation.
