    //C++ Operators
    //  Operators specify an evaluation to be performed on one of the following:
    //    One operand (unary operator)
    //    Two operands (binary operator)
    //    Three operands (ternary operator)
    //  The C++ language includes all C operators and adds several new operators.
    //  Table 1.1 lists the operators available in Microsoft C++.
    //  Operators follow a strict precedence which defines the evaluation order of
    //expressions containing these operators.  Operators associate with either the
    //expression on their left or the expression on their right;    this is called
    //“associativity.” Operators in the same group have equal precedence and are
    //evaluated left to right in an expression unless explicitly forced by a pair of
    //parentheses, ( ).
    //  Table 1.1 shows the precedence and associativity of C++ operators
    //  (from highest to lowest precedence).
    //
    //Table 1.1   C++ Operator Precedence and Associativity
    // The highest precedence level is at the top of the table.
