Class creation and string manipulation

This lab will give you some more practice with writing and using classes. It will also provide an opportunity to review the string class in C++. It is based on an assignment created by Lucia Moura at the University of Ottawa.

• Topics to be review before you start:
• Creating classes in C++
• *.cpp and *.h files
• constructors / destructors
• private and public elements
• The string class
• #include <string>
• string operations (getline, substr, find, length, size)
• reading from a file with fixed length fields

• Download the following files:
• lab3.cpp
• students.dat
• Look over the lab3.cpp file. Notice that it makes use of a class named student.
• Write both the header(student.h) and the implementation(student.cpp) for this class student with the following specification:
• Private attributes
            - long int number;              // the student's id
            - string   name;                // the student's name
• Public operations
            - Student()                     // constructor
            - virtual ~Student()            // destructor
            - long int getNumber()          // get the name
            - void setNumber(long int)      // set the name
            - string getName()              // get the number
            - void setName(string)          // set the number

• Complete the method void readStudent(istream& input, Student& s) inside lab3.cpp. This method should :
• read a line from the input parameter and store it in a string
• extract the name and number of the student from this string
• set such name and number for student s
• Use the file students.dat as the input file
• This file has a number of lines, each one storing a student where the first 7 digits are the student number and the next 21 the student name:
• 9999999XXXXXXXXXXXXXXXXXXXXX
