Hello,
I have a problem with using a copy constructor to convert an object of a
templated class to object of another templated class. Let me first
include the code (my question is below):

I am using push_back to place a class object into a vector. This class
contains data members that are pointers to a char string. When I use
push_back, I believe a copy of the object is first made, and then deposited
into the vector.
But I want this copy to not mereley copy the pointer to the char string, but
rather, I want to malloc new space, and make a copy of the char string.
The default copy constructor is defined as

I have a String class (I know I am re-inventing the wheel, yes I have
heard of boost, and of QString).
My copy constructor does a deep (strcpy) of the char *_buffer member.
I have a member function func(const String ¶m). When an actual
String is passed as the param this is nice and efficient.
I have a constructor which takes a const char* as an argument. And

Hello,
I have encountered a strange problem and I hope you can help me to
understand it. What I want to do is to pass an array of chars to a
function that will split it up (on every location where a * occurs in
the string). This split function should allocate a 2D array of chars
and put the split results in different rows. The listing below shows
how I started to work on this. To keep the program simple and help
focus the program the...

I'm confused about the two ways of string copy below. The first one
(two functions) works; the second doesn't. Can anybody explain the
reason to me? Thanks a lot.

Hi,
I need to see the output of the program when no copy
constructor is used. Since by default, there is an implicit one, how
should i perform the override, so as to totally remove the copy
constructor functionality.
Consider the following code.

A few days a ago I posted my code for a deep copy pointer which
doesn't require the pointee object to have a virtual copy constructor.
I need help with checking that it was exception safe and exception

lines of code
and more cleaner design, not over engineered like mine.

Hi all ,
A question to the C++ fraternity , Why the Copy constructor ?
Was suggested in Effective C++ , In Case the Object contains a
Char* , a assignment operator = makes the two object point to the
same address . In this case any Of the two Object is destroyed a
memory leak occurs as one of the object stays on the Heap . My
experiments on the same have proved otherwise .
