Pointer Variables

Justification

• The idea is that the difference between a pointer, object, and a reference to an object is important for understanding the code, especially in C++ where -> can be overloaded, and casting and copy semantics are important.
• The * belongs near the variable name since its not cumulative to other declarations of the same line. This convention follows closely the way c++ behaves in this matter.

  Example 2-7. Placement of * during pointer declarations

  BAD: int* p_var; GOOD: int *p_var;

QString *p_name = new QString;
QString *p_name; // note, only pName is a pointer.
QString name;
QString address;
