c++ class woohoo

[sde]

i started my classes and it's pretty cool .. i'll write some really beginner nums on the stuff we are doing... they are a good introduction for c++ newbs. i like it.

sounds great! let us all bask in the glow of your c++ enlightened mind...

2 words:

HELLO WORLD!

[redhead]

No its C++, we need to be more Object Oriented:

class world{
   void world(){ cout << "Hello world" << endl;};
   void ~world(){ cout << "Goodbye cruel world" << endl;};
};

int main(){ world my_world; return 0;}

Note: the above code has not been tested..

I really need to learn C++ myself. I'm pretty proficient with C, but I just never really learned how to use classes. Hopefully I'll get the time to do it some time soon.

Actualy, first I wanted to make a string overloading and a cout overloading, so it would be something like:

int main(){
world hello;
String world = hello;
cout << world;
return 0;
}

Given the cout would allways print "hello" and the world class would allways hold "world" as a string.

But I thought it was too much for a beginner class

what exactly does overloading mean?

A small example:

class someclass{
   String name;
  public:
    void someclass() { name="";};
    void someclass(String Name=""){name=Name;};
};

The create function for someclass is overloadet, so if you use:

int main(){ 
   someclass test; 
   someclass test1("new class");
  return 0;
}

Then in test1 case, it will use the second create function in someclass, thus assigning the name variable to "new class" the same thing is possible with allready created functions like cout you just need to create it as an operator to the given class you're creating, for the cout << it would be cout::operator << { /* what ever to do */}

now this statement i understand .. the overloading is a little over my head as of now .. maybe in a couple weeks i'll look back to this post and perhaps understand.

thanks for the explination

overloading is simple.. in java for example:

public void GiveMeVal(int x)
{
    system.out.println("x is an int equal to:" + x);
}

public void GiveMeVal(String s)
{
   system.out.println("s is a string equal to:" + s);
}

so there are TWO "methods" with the same name (GiveMeVal) but have a DIFFERENT parameter list (int x and String s).

So if we call: GiveMeVal(10); we will get "x is an int equal to: 10"
and if we call...: GiveMeVal("ten"); we get "s is a string equal to: ten"

easy!!

hmm .. thanks =) the lights are turning on slowly
