Consider the following correct segment of a correct C program:

Suppose the unary ! operator is an overloaded member function of class String. For a String object s, which function call is generated by the compiler when it finds the expression !s?

a. s.operator!() b. s.operator!( default_value1, default_value2,…) c. operator!( s ) d. A compiler error results because no arguments are given.

A programmer must do the following before using an array:

a. declare then reference the array. b. create then declare the array. c. create then reference the array. d. declare then create the array.
