Implement a Car class that includes data members to represent a car's make (e.g., Honda), model (e.g., Civic), production year, and price. The class interface includes methods that provide appropriate access to the data members (e. g., a method to set the car's model or to get its price). Create a Text class that contains a string object to hold the text of a file. Give it two constructor: a default constructor and a constructor that takes a string argument that is the name of the file to open. When the second constructor is used, open the file and read the contents into the string member object. Add a member function contents() to return the string so (for example) it can be printed. In main(), open a file using Text and print the contents. Create a class that contains four member functions, with 0,1.2, and 3 int arguments, respectively. Create a main() that makes an object of your class and calls each of the member functions. Now modify the class so it has instead a single member function with all the arguments defaulted. Does this change your main()? . Implement a Complex class and overload the equals (-), not equal (!=), unary minus (-), and right shift operator (>>) for the Complex class. Complex numbers z1=a+bi and z2=c+di are equal if and only if a equals c and b equals d. If z = a+bi is a complex number, -z equals -a-bi. Overload the right shift operator for input. Implement a Clock class. Overload the function call operator to set the time for the Clock class. The overload should behave similarly to the constructor. Also overload = and != so that two Clocks can be compared. Two Clocks are equal if and only if they have the same time. . Suppose that Matrix2 is a two-dimensional matrix class. Overload the subscript operator [] so that if m is a Matrix2 object, m[i][j] reference the cell in the ith row and jth column.
