CSCI 270 Preliminary Quiz ( 7 Jun ) Name _________________________
Fall 2004
Given this partial class:
class Course
{
public:
int getCreditHours();
float getLabFee();
// other function prototypes will go here
private:
string dept; // department offering the course, like CSci
int number; // course number, like 270
int creditHours; // # of credit hours a student earns, like 3
bool semOffered[8]; // semesters this course is usually offered where
// subscript 1 = spring, 3 = summerI, 4 = summerII, 7 = fall
float labFee; // amount charged for a lab fee, like 25.00
}
1. What would be the name of a constructor function for this class? _____________________
A constructor function always has the same name as the class:
Course(); // default constructor for this class
Course(int number, int creditHours, float labFee);
Also constructors have no type. A constructor is neither a value-returning function
nor a void function.
2. A client program using this class could legally use this declaration:
int dept; yes no
Yes, a client program may declare variables which have the same names as private
variables in a class included by the program. Since the private variables are not
directly accessible by the client program, there is no conflict. In fact, even if dept
was a public variable of the Course class there would still be no conflict as class
variables are part of and accessed through instances of the Course objects.
3. Show how a client would declare an array of 10 Course variables.
Course courses[10];
