3 small programming questions Solution

1 :

Write the header file Car.h for the Car class. The Car class has three data members: miles_per_gallon (double), fuel (double), and model (string). The Car class has a constructor that initializes each data member.  The Car class has four additional member functions:

get_model : no parameters, returns model

drive : double miles parameter, returns nothing

add_fuel : double gallons parameter, returns nothing

low_on_fuel : no parameters, returns true or false

Do not provide the implementation of the member functions.

2:

Write the source code file

Square.cpp

. Include necessary header files and implementation of each member function of the following

Square

class.    

class Square

{

public:

    Square(double initial_length, string initial_color);

    doubleget_length() const;

    stringget_color() const;

    doubleget_area() const;

private:

    double length;

    string color;

};

The area of a square is length x length.

3:

Write a void function named sort2 that takes two string parameters and sorts them. The function swaps the values of the string parameters if the 1^st string is lexicographically greater than the 2^nd string and otherwise leaves the strings unchanged. For example:

string s1 = "Orange";

string s2 = "Apple";

sort2(s1, s2);      // now s1 is “Apple" and s2 is "orange"
