Sample text

Simple" in this case means the class does not have any of the following: • • • • user-declared constructors private or protected non-static data members base classes virtual functions To initialize an aggregate, you can supply multiple values in curly braces, as described in the following sections. A POD object is a special case of an aggregate. ) 53 To initialize an aggregate of class type, supply an initial value for each non-static data member, separated by commas, enclosed in curly braces.

Typedef int_ptr (*int_ptr_func)(int_ptr); // Declare a function pointer type for a function that // returns int_ptr and takes two parameters: the first // of type int_ptr and the second of type int. typedef int_ptr (*func_ptr)(int_ptr_func, int); // Declare an array of 10 func_ptrs. func_ptr fp[10]; Member pointers Pointers to members (data and functions) work differently from other pointers. The syntax for declaring a pointer to a non-static data member or a non-static member function requires a class name and scope operator before the asterisk.

An initializer list can be empty, which means all members are initialized to their defaults, which is different from omitting the initializer entirely. The latter causes all members to be left uninitialized. 0 Only the first member of a union can be initialized. value Initializing arrays Initialize elements of an array with values separated by commas, enclosed in curly braces. Multi-dimensional arrays can be initialized by nesting sets of curly braces. It is an error if there are more values than elements in the array; if an initializer has fewer values than elements in the array, the remaining elements in the array are initialized to zero values (default constructors or zero).
