Explicit Type Conversion

The following syntax use is not allowed when using explicit type conversions on an HC(S)08 compiler:

i = int();//A simple-type-name followed by a pair of parentheses

The following explicit type conversion features are unsupported at this time:

• Casting reference to a volatile type object into a reference to a non-volatile type object. Example:

  volatile int x = 1;
  
  
  volatile int& y= x;
  
  
  if((int&)y != 1);
  
  
  -------^-------------------------ERROR
  

• Converting an object or a value to a class object even when an appropriate constructor or conversion operator has been declared. Example:

  class X {
  
  
  public:
  
  
        int i;
  
  
        X(int a) { i = a; }
  
  
  };
  
  
     X x = 1;
  
  
     x = 2;
  
  
  -----^-------------------ERROR: Illegal cast-operation
  

• Explicitly converting a pointer to an object of a derived class (private) to a pointer to its base class. Example:

  class A {public: int x;};
  
  
  class B : private A {
  
  
  public:
  
  
        int y;
  
  
  };
  
  
  int main(){
  
  
        B b;
  
  
        A *ap = (A *) &b;
  
  
  ---------------^----- ERROR: BASE_CLASS of class B cannot be accessed
