    class template Convert which can convert itself to any data type

    Code:
    template<class T>
    class Convert
    {   
       T data;
    public: 
       Convert(const T& tData = T()) : data(tData)
       { }
    
       template<class C>   
       bool IsEqualTo( const C& other ) const      
       {        
           return data == other;   
       }
    };
    Code:
    template<class T>
    operator T() const
    {
        return data;
    } 
    
    Convert<int> IntData(40);
    float FloatData;
    double DoubleData;
    
    FloatData = IntData;
    DoubleData = IntData;
    Code:
    Convert<int>::operator<float> float();
    Convert<int>::operator<double> double();
    ) ----------------------------------------------------
    Why do we use operator? Is float and double function names below?
    Code:
    Convert<int>::operator<float> float();
    Convert<int>::operator<double> double();
    Thanks in advance

    This doesn't make sense. The cast operator can only be defined as a class member function.
    What are you trying to achieve at a higher level?

    Please put [code][/code] tags around your code to preserve indentation and make it more readable.
