I have a class that holds an "error" function that will format some text. I want to accept a variable number of arguments and then format them using printf.
Example:
class MyClass
{
public:
void Error(const char* format, ...);
};
The Error method should take in the parameters, call printf/sprintf to format it and then do somethi...

Hi all,
I have to do enhancements to an existing C++ project with above 100k lines of code.
My question is How and where to start with such projects ?
The problem increases further if the code is not well documented.
Are there any automated tools for studying code flow with large projects?
Thanx,

Hello!
I need to mix Objective-C and C++. I would like to hide all the C++ stuff inside one class and keep all the others plain Objective-C. The problem is that I want to have some C++ classes as instance variables. This means they have to be mentioned in the header file, which gets included by other classes and C++ starts spreading to ...

Hello,
When,i try to assign null value to my pointer,it sometimes crashes on that line. The code is

This is not reproducable,100%,but it occurs frequently. Can anybody help in this?

Hello,
We have the following code fragment:
char tab[2][3] = {'1', '2', '\0', '3', '4', '\0'};
printf("%s\n", tab);
And I don't understand why we don't get an error / warning in the call to printf. I DO get a warning but not an error, and the program runs fine. It prints '12'.
printf is expecting an argument of type char *, i.e. a po...

I'm dealing with a large code base that uses the following construct throughout
class MyClass
{
public:
void f(int x);
private:
int x;
};
void MyClass::f(int x)
{
'
'
this->x = x;
'
'
}
Personally, I'd always used and hence prefer the form
class MyClass
{
public:
void f(int x);
private:
int _x;
};
void MyClass::f(int x)...

Is there any library for distributed in-memory cache, distributed tasks, publish/subscribe messaging? I have used Hazelcast in Java, I would like something similar.

In this question asking how to adjust the iterator to an STL container by 2 elements two different approaches are offered:
either use a form of arithmetic operator - +=2 or ++ twice
or use std::advance()
I've tested both of them with VC++ 7 for the edge case when the iterator points onto the last element of the STL container or beyon...

I know a solution would be to use VS 2005 or 2008, but that's not an option at the moment. I am supposed to write an extension to the VS 2003 C++ debugger to improve the way it displays data in the watch window. The main reason I am using a DLL rather than just the basic autoexp.dat functionality is that I want to be able to display thin...
I'm interested in learning more about distributed computing and how to do it - mostly in C++ but I'd be interested in C# as well.
Can someone please recommend some resources? I know very little to nothing about the topic so where should I start?
Thanks.
