		int x[50]; int y[50];



		there is no aggregate assignment of y to x:



		x = y; // No



		To copy array y into array x, you must do it yourself, element by element:



		for (index = 0; index < 50; index++) x[index] = y[index];



		Similarly, there is no aggregate comparison of arrays:



		if (x == y) // No



		nor can you perform aggregate I/O of arrays:



		cout << x; // No



		or aggregate arithmetic on arrays:



		x = x + y; // No



		(C++ allows one exception for I/O, as we discuss in Chapter 12. Aggregate I/O is permitted for strings, which are special kinds of char arrays.) Finally, it's not possible to return an entire array as the value of a value-returning function:



		return x; // No



		The only thing you can do to an array as a whole is to pass it as a parameter to a function:



		DoSomething(x);
