#include <iostream>
#include <vector>
#include <string>
using namespace std;

class Vechile
{
public:
virtual void print(){
cout << endl
<< "Name: " << name << endl
<< "Color: " << color << endl
<< "Type: " << type << endl;
}
virtual void horn() = 0;
protected:
string name;
string color;
string type;
};

class Ship : public Vechile
{
public:
Ship( string n, string c, string t ){
name = n;
color = c;
type = t;
}
~Ship(){}
void horn(){
cout << "Ship~" << endl;

class Car : public Vechile

public:

class Truck : public Car
{
public:

int main()

for ( int i = 0; i < 3; i++ )

vec[i] -> horn();
