WebArrays (including C strings) can not be initialized using initialization lists. Initializing an object this way results in a constructor call. For example, if a class called employee has a date object called hire_date as one of its data members, we could use an initializer list to initialize the hire_date data member in the employee constructor: WebInitialization Lists and Primitive Types. It turns out that initialization lists work to initialize both user-defined types (objects of classes) and primitive types (e.g., int). When the field is a primitive type, giving it an argument is equivalent to assignment. For instance, 1. 2. 3.
