I NEED HELP QUICK PLEASE

Please do it in C++

Design a program with vehicle class as base class and two classes: car and truck derived from vehicle. The vehicle class has a method to set the type of vehicle. The car and truck classes have two methods, one to set name and the other one to set speed. Write an OverSpeed exception class that checks the speeds of cars and trucks. The overspeed limit of cars = 70 and that of truck = 50.

// Exception class

class OverSpeed {

//Constructor to create OverSpeed s;

// A method to display message

}

// Base class

class vehicle{

public:

setType(string type);

private:

string type;

}

//implement setType(string type);

//Derived class1

class car: public vehicle {

public:

setName(string name);

setSpeed(int speed);

private:

string name;

int speed;

}

//implement setName(string name);

//implement setSpeed(int speed); // OverSpeed exception class

//Derived class2

class truck: public vehicle {

public:

setName(string name);

setSpeed(int speed);

private:

string name;

int speed;

}

//implement setName(string name);

//implement setSpeed(int speed); // OverSpeed exception class
