... usual operator syntax, x + 7 , that C++ uses for types such as int and dou- ble . And one way to view a high-level language, such as C++, is as a way to make people comfortable ... Thus, this syntactic sugar is probably a good idea; at the least, it is a well-entrenched idea. In C++ you can overload the operators, such as + and == , so that they work with oper-...

... confused and place the * on the int, the problem is the same but is more difficult to notice. C++ allows you to place the * on the type name, such as int, so that the following is legal: int* ... variables, but in fact only p1 is a pointer variable; p2 is an ordinary int variable. As far as the C++ compiler is concerned, the * that is attached to the identifier int may as well be...
