Define a class for complex numbers. A complex number is a number of the form a + bi, where a and b are double type data and I is a number that represents the quantity √-1. Class name is Complex. Name the private member variables real and imaginary. Default constructor that initializes an object to 0 (that is, 0 + 0i) Constructor with two parameters Other functions (See next slide)

A(n) ____________ is one instance or variable of a class.

(Conversion) Write a C++ program that converts gallons to liters. The program should display gallons from 10 to 20 in 1-gallon increments and the corresponding liter equivalents. Use the relationship that 1gallon=3.785liters.

Mark the following statements as true or false. All members of a struct must be of different types. (1) A struct is a definition, not a declaration. (1) A struct variable must be declared after the struct definition. (1) A struct member is accessed by using the operator :. (2) The only allowable operations on a struct are assignment and member selection. (2) Because a struct has a finite number of components, relational operations are allowed on a struct. (2) Some aggregate input/output operations are allowed on a struct variable. (2) A struct variable can be passed as a parameter either by value or by reference. (4) A function cannot return a value of the type struct. (4) An array can be a member of a struct. (6, 7) A member of a struct can be another struct. (8)
