Initialising a Reference variable present in a class

vicky_brsh · #1 16-May-2008, 03:40

Hi All,

As far as i know we have to initialise a reference when we declare it.

But, how can we initialise a variable that is present as a member of a class ?

Can any one help to solve this problem ?

Thanks and Regards
Vikram

Do you know what a class constructor is? This is the method that fires when your class is created. That is the best place to put initialization routines in. For example:

CPP / C++ / C Code:

class Example
{ private:
    int x;
  public:
    Example();
    ~Example();
};

// Constructor
Example::Example()
{ 
  // Initialize x to 10  
  x = 10;
}

// Destructor
Example::~Example()
{
  // Free any class memory that was allocated with new or malloc/calloc here
}

Hi ,

Oops sorry there was a mistake in the question .

What i wanted to know is how to initialise a Reference variable present as a member variable in the class.

whether it is right to have a reference variable as a member variable in the class or not ?

Thanks and Regards
Vikram

That is absolutely correct.

You declare it (and initialize it) in the class constructor(s). (Where else could you do it?). Syntax and semantics are exactly the same as for any other reference variable.

How about giving an example of exactly what you want to do and what you don't understand about it? Be specific.

Dave
