Inheritance from template problem
|
| |
Hello,
My inheritance problem is my uncle left me $10 million, but to get it
I have to spend the night in an isolated haunted house. My uncle
didn't like me. I think it's a plot to kill me! :o)
Seriously, when I compile the following code, I get the error: "B::i
is not accessible" on the line "f = Tptr->i". It compiles fine if "i"... more »

reduce c++ vector size
|
| |
Hi,
I wrote a program in which I define a vector of some class objects.
Initially the vector has size and capacity both set to 0.
The moment I add an element to the vector the size is 1 and the capacity
jumps to 32 elements.
This is causing a huge overhead on my program since I need to use many such... more »

Indirection operator and write access
|
| |
...
...
What does "showing write access on x" mean?
...
You can't overload *. I can't see how x could me modified here, but note
that anything can happen inside the version of operator<<(ostream&,...)
called at that point. Here is an example:
class X { ... };
class Y {
public:
Y(const X & x) { ... }... more »

Indirection operator and write access
|
| |
...
You can't overload the operator* for pointers. That's a built-in one. Once you dereference *x, you get a reference to the object. The pointer variable does not have any play in dealing with that, so it seems that the write access to 'x' itself has nothing to do with '*x'.

Access Violation Problem
|
| |
I have the following code that compiles but produces a "Access violation reading location..." runtime error when executed. I tried casting the first statement to (char*), but that produced the same fault. I suppose the problem lies with the use of the "const char" in the parameter declaration, but I've been trying to follow the examples I see... more »

Boost function/bind problem

Hello there.
I am trying to use the Boost function type in conjunction with bind, in order to
homogenise some code.

class C2
{
public:
void
otherOp(int i, float f) { /* ... */ } ;
