Thread: a little help!

can someone out there explain what is the object,constructors and destrustors? if can,write a simple program that contain three thing that i mentioned up there.i just wanna to know what is it and the functinality of it,thanks!

Example object myClass.

Code:

class myClass
{
private:
   int intInt;
   long longLong;
public:
   myClass();                 //this is the constructor
  ~myClass();               //this is the destructor
}

myClass::myClass()     //constructor
{
   intInt=0;
   longLong=0;
}

myClass::~myClass()  //destructor
{
}

The constructor is a member function of the class that has the same name of the class and can't return a value. It's called when the object is created. ie:

Code:

myClass ClassOne;  //constructor is called here.

The destructor is the opposite of the constructor and has the same name as the constructor except that it starts with a ~. It's called when the object is destroyed.

Constructors usually set the initial values of the member variables (like setting a pointer to NULL) and destructors do the clean-up (like deleting the pointer and resetting it to NULL).
