Lab 2

  1. Write a class in C++ that has the following definition: 
class NumberList
{
    int numbers[10];
    int count;
public:
    void Init();          // count will be 0
    bool Add(int x);      // adds X to the numbers list and increase the data member count.
                          // if count is bigger or equal to 10, the function will return false
    void Sort();          // will sort the numbers vector
    void Print();         // will print the current vector
}

Organize the code in the following way:

  • a header file called NumberList.h
  • a cpp file called NumberList.cpp that contains the source code for class NumberList
  • a main file called main.cpp that contains the main function and has an example on how to use NumberList. The example must include using all methods from the class. make sure that precompile headers are NOT used (for Visual Studio setup).
  1. Design a C++ class (following the previous problem) that reflects the properties of a student. The class should include the following:
  • methods to set and get the name of the student
  • methods to set and get the grade for mathematics (a grade must be a float value from 1 to 10)
  • methods to set and get the grade for English (a grade must be a float value from 1 to 10)
  • methods to set and get the grade for History (a grade must be a float value from 1 to 10)
  • a method that retrieves the average grade
  • 5 global functions that compares two students in terms of name, grades, average. If two students are equal the return value of such a function will be 0. If the first student is bigger than the second one, the return value will be 1, otherwise -1.

Make sure that you have the following:

  • a header file for the class
  • a cpp file for the methods specific to the class
  • a header file for the global functions
  • a cpp file for the global functions implementation
  • a main.cpp file that shows how the methods and global functions can be used.
