Initialization Features

The compiler does not support the following initialization features:

• When an array of a class type T is a sub-object of a class object, each array element is initialized by the constructor for T. Example:

  class A{
  
  
  public:
  
  
        A(){}
  
  
  };
  
  
  class B{
  
  
  public:
  
  
        A x[3];
  
  
        B(){};
  
  
  };
  
  
  B b; /*the constructor of A is not called in order to initialize the elements of the array*/
  

• Creating and initializing a new object (call constructor) using a new-expression with one of the following forms:
  • (void) new C();
  • (void) new C;
• When initializing bases and members, a constructor's mem-initializer-list may initialize a base class using any name that denotes that base class type ( typedef); the name used may differ from the class definition. Example:

  struct B {
  
  
        int im;
  
  
        B(int i=0) { im = i; }
  
  
  };
  
  
  typedef class B B2;
  
  
  struct C : public B {
  
  
        C(int i) : B2(i) {} ;
  
  
  ---------------------^------------------ERROR
  
  
  };
  

• Specifying explicit initializers for arrays is not supported. Example:

  typedef M MA[3];
  
  
  struct S {
  
  
        MA a;
  
  
        S(int i) : a() {} 
  
  
  -----------------------^----------ERROR: Cannot specify explicit initializer for arrays
  
  
  };
  

• Initialization of local static class objects with constructor is unimplemented. Example:

  struct S {
  
  
        int a;
  
  
        S(int aa) : a(aa) {} 
  
  
  };
  
  
  static S s(10);
  
  
  ---------^-------------ERROR
