Writing a LinkedList destructor?
Is this a valid LinkedList destructor? I'm still sort of confused by them. I want to make sure I'm understanding this correctly. LinkedList::~LinkedList() { ListNode *ptr; for (ptr = head; head; ptr = head) { head = head->next delete ptr; } } So at the beginning of the loop, pointer ptr is set to hold the add...
C++ STL map I don't want it to sort!
This is my code map<string,int> persons; persons["B"] = 123; persons["A"] = 321; for(map<string,int>::iterator i = persons.begin(); i!=persons.end(); ++i) { cout<< (*i).first << ":"<<(*i).second<<endl; } Expected output: B:123 A:321 But output it gives is: A:321 B:123 I want it to maintain the order in whi...
Using boost.assign on collection of shared_ptr
Consider the following snippet: class Foo { public: Foo( int Value ); // other stuff }; std::list< boost::shared_ptr< Foo > > ListOfFoo = list_of( 1 )( 2 )( 3 )( 4 )( 5 ); This does not work out of the box. What is the simplest way to make this work, or is there any method to assign values to ListOfFoo as simple as that? ...

Make an executable at runtime
Ok, so I was wondering how one would go about creating a program, that creates a second program(Like how most compression programs can create self extracting self excutables, but that's not what I need). Say I have 2 programs. Each one containing a class. The one program I would use to modify and fill the class with data. The second fil...

Storing data effectively
hi everyone, maybe i'm having stupid question as always, but somehow i can't google out how should I store variables so it's effective. Our teacher on c++ just by the way droped something about how could size of the stored data type affect the speed of storing it (like searching for closest sufficient continuous block of memory) and I w...

On a related note, how do you guys handle changing version numbers in documentation, the application, etc. without chan...
C++ Template Quine
It is known that C++ templates are turing complete. As such it should be possible to output a quine that is essentially rendered at compile time. Does anyone know if such a quine has been written yet or where I could find one. ...
