I need someone highly knowledgeable in C++. Of course, I will be paying for the work and solution. The time limit is about a day or two. I'll be pming you the problem and specifications.
Please post or pm me if you are interested. It will be worth your time:fg.

Post your problems

Iso expertise.

Mens is excellent with programming, PM him,

uh? i guess that means list all the ways i am better than you...

i know c, c++, vb6, vb.net c#.net, pascal, delphi, asm 32bit at&t system v syntax, as well as some knowledge in php, ruby, perl, and python. i have knowledge varying subjects such as encryption, sockets, and understand basic and advanced logic control schemes.

dont feel like helping now because you made me type instead of just typing your fucking problem. prolly has to do with some bot anyways.

It goes without saying, anyone who views this thread would be better than me, or why else would they be here?
I guess I'll just post my questions instead ._.

Here's the question;
The following classes and main are from
http://cboard.cprogramming.com/cplusplus-programming/100352-array-base-abstract-class-problem.html

#include <iostream>

class Base{

public:

virtual void doSomething(){
std::cout << " - - - - " << std::endl;
}

};

// - - - - - - - - - - - - - - - - - - - - - - - -

class Extended : public Base{

public:

void doSomething(){
std::cout << "Doing something..." << std::endl;
}

};

// - - - - - - - - - - - - - - - - - - - - - - - -


// ------ NEW
void helper_func(Base* objs[]) {
objs[0]->doSomething();
}
//-----

int main(int argc, char* argv[]){

Base baseObj;
Extended *extensionObj = new Extended;

Base *objs[2];
objs[0] = &baseObj;
objs[1] = extensionObj;

objs[0]->doSomething();
objs[1]->doSomething();

///--- new
helper_func(objs);
//----
return 0;
}


Now the question is, if we take at the routine helper_func and the call to it in main, how would I be able to replace:

void helper_func(Base* objs[])
to
void helper_func(Base& ...) where .. is whatever, but Base& must be there - since I want to use a reference. (This is a specification).

In reflection of this change, what would be the change to the call?: helper_func(objs);

I still want it to do exactly the same thing as above, where the array of pointers to a base can be accessed "normally" in another function.

Question 2: I want to clarify if the following will delete the memory reserved.
delete objs[0];
delete objs[2];

Thank you~
100 fg to the first correct solution.

You can use code tags

helper func - depends on what you want the reference to refrence

if it's a single object, just do


and call it like this:
helper_func(*objs[0]);

if you want to reference the array instead

And you don't change your calling code either, but I don't think that's what you wanted.

Q2:
You don't need to delete [0], because it has automatic storage class and [2] is out of bounds of your array. You should delete [1] though.

Q2:
Ah yes, my mistake on deleting 2, meant 1

For Q1, it still isn't what I need.


I need the parameter to be (Base& ...) where .. can be replaced with a parameter name. So i want to pass by reference.

The other solution;


Is kind of what I want but I want it for the whole array. Thus I want to access obj[2] as well, etc.

The point is so I can access the whole array in the other function and change it as well. And not make a copy of it.

You already are not making copying the array. You can't pass an array of references, but you can simplify your syntax a little and use



With calling code being

helper_func(objs[0])

or

helper_func(*objs)

If you really want a reference, try using a container cass like vector.
