Read-only data members

Read-only data members

One means of achieving this (proxies are another, properties are a third) is by providing a public data member which is a const reference to an actual (non-const) private data member:

        class ArrayDemo
        {
        private:
        	int myCount;

        public:
        	const int& count;

        	ArrayDemo(void)
        	: myCount(0)
        	, count(myCount)
        	{}
        };
