When you need a constant integer member in an object, the easiest way to create one is by using a nameless enum, which can be used like any

  const int: class vector {	int v_size;	enum {MAX = 1024}; //nameless enum 	char *p;	public:	vector() {p = new char[MAX]; }	vector( int size) {if (size <= MAX)				 	p = new char[size] ;		      	else 					p = new char[MAX]; }}
