operator overloading

[gizzmo]

Hi, How can I overload operator [] and = so that I could do an assignment like

object[1] = something;
object[2] = sonethingelse;

what would you want to happen in these cases? What types of class is 'object' an instance of? Since you want to overload [] im guessing 'object' is not an array but be careful when considering overloading an operator, you should only overload if the meaning of the operation remains clear, otherwise create a clearly named method to perform the operation.

You need to be more specific. I'm going to take a shot in the dark and suggest this code:

class OBJECT
{
    public:
        OBJECT( void );
        ~OBJECT( void );

    protected:
        struct INFORMATION
        {
            int _iLength;
            int *_pResources;
        } _Info;

    public:
        int &operator [ ] ( const int iIndex ) const;
};

OBJECT::OBJECT( void )
{
    try
    {
        // Attempt to allocate a block of memory.
        this->_Info._pResources = ( new int[ 5 ] );

        for( int iLoop( 0 ); iLoop < 5; iLoop++ )
            // Any initializing value will do here.
            this->_Info._pResources[ iLoop ] = ( iLoop + 2 ); 

        this->_Info._iLength = 5;
    }

    catch( std::bad_alloc )
    {
        this->_Info._pResources = NULL;
        this->_Info._iLength = 0;
    }
}

OBJECT::~OBJECT( void )
{
    delete [ ] this->_Info._pResources;
}

int &OBJECT::operator [ ] ( const int iIndex ) const
{
    // Check if the allocator is in use.
    if( !this->_Info._pResources )
        // Throw an exception or something...

    // Validate the index.
    if( ( iIndex >= 0 ) && ( iIndex <= ( this->_Info._iLength - 1 ) ) )
        return this->_Info._pResources[ iIndex ];

    else
        // Throw an exception here or something...
}

int main( )
{
    OBJECT Object;

    Object[ 0 ] = 45;

    std::cin.get( );
    return 0;
}

This is what I've come up with, and it might help you. Without more information, I cannot give much help.

If you want to store multiple data types at once you might consider a struct.
struct name
{
int intArray[]
char charArray[]
etc...
};

I think you misread the original post, Edithsong.
