Question

Write a class Car that contains the following attributes:

• The name of car
• The direction of car (E, W, N, S)
• The position of car (from imaginary zero point) The class has the following member functions:
• A constructor to initialize the attributes.
• Turn function to change the direction of car to one step right side (e.g. if the direction is to E,it should be changed to S and so on.)
• Overload the Turn function to change the direction to any side directly. It should accept the direction as parameter.

Answer 1

Below is your program

#include <string.h>

#include <iostream>

using namespace std;

class car

{

int pos;

char car_name[20];

char dir;

public:

void turn();

void move(int);

void turn(char);

car(char name[], char d, int p)

{

strcpy(car_name,name);

dir=d;

pos=p;

}

void display() {

cout<<"\nCar Name: "<<car_name<<", Position: "<<pos<<", Direction: "<<dir<<endl;

}

};

void car :: turn()

{

switch(dir)

{

case 'N' : dir='E';

break;

case 'E' : dir='S';

break;

case 'S' : dir='W';

break;

case 'W' : dir='N';

break;

default : cout<<"THE DIRECTION IS INCORRECT !!!";

}

}

void car :: turn(char d1)

{

dir=d1;

}

void car :: move(int p1)

{

pos+=p1;

}

int main()

{

class car c("NANO",'N',100);

char ch;

char dir;

int p1,ch1;

c.display();

bool done = false;

while(!done)

{

cout<<"\n1.change in direction sequntially";

cout<<"\n2.change in direction randomly";

cout<<"\n3.change in position of the car";

cout<<"\n4.Exit";

cout<<"\nEnter your choice\n";

cin>>ch1;

switch(ch1)

{

case 1:

c.turn();

break;

case 2:

cout<<"input the required direction\n ";

cin>>dir;

c.turn(dir);

break;

case 3:

cout<<"\nEnter the require position\n";

cin>>p1;

c.move(p1);

break;

case 4:

done = true;

break;

default:

cout<<"\nWrong choice";

}

cout<<"Car Details: "<<endl;

c.display();

}

return 0;

}

Output
