Chapter 13.5, Problem 13.27CP
Program Plan Intro
The “write” member function:
The “write” member function is one of the file stream object’s functions and it is used to write the binary data or raw data in the specified file.
The syntax of the “write” function is as follows:
filestreamobject.write(address,size)
- The “filestreamobject” is the object name of a stream.
- The argument “address” indicates the part of the memory that is to be written on the specified file. This argument must be address or pointer of a char.
- The argument “size” indicates the number of bytes which is to be written. This argument must be an integer.
Typecast – Converts the value of one type into another type.
The type cast which is used to convert the pointer of one type to another type is “reinterpret_cast”.
- The basic format for “reinterpret_cast” as follow as:
- reinterpret_cast <dataType>( argument)
- Here, the “dataType” is the type that user converting to, similarly the “argument” is the value which the user wants to convert.

Task:You have to write a program to store information of university students. There can be many students in university, so you can make a Student class and objects of class Student to store information. The university is interested in storing information about student’s name, enrollment, department, class, CGPA and gender. You can store this information as data member values for each object. But as you already know you cannot directly access data members of a class, so you need to make member functions to access data members. You can make as many member functions as you want. There are no restrictions.
The University is interested in knowing the student’sname with highest CGPA in a specific class. For example if you entered information of 10 students from class BSIT 2 and information of 5 students from class BSIT 3, and it is asked to find name of student with highest CGPA in BSIT 2 then your program must be able to find details of highest CGPA student from…

- Answer everythingarrow_forwardFirst programming homework Create a class of records for a gradebook called Rec. The data should be private, and should include a firstname, lastname, array of three grades, and a field for average grade. Build two constructors: a default constructor and a constructor that takes the first and last name. Build a function to read the data, either from a file or from cin. The read function reads the two names and three grades, but does not read the average grade. Build a write function that writes the data either to a file or to cout. The write function prints all of the data on one line with spaces between fields. Build a function to calculate the average grade field. Build an overloaded operator == to compare two records. This should be implemented as a friend function. Declare the constructors and functions in the body of the class, but implement them outside the class.
