Question

#2 You are going to add more code to carClass.cpp. 0. Make sure you finished the lab part: goForward, turnRight(), getDirection(), getXO, getY() and get Modelo 1. Preparation: In the last lab, we tested our functions using cl. Comment out that section. Create c2 with any make and model. int main() Car cl("Toyota", "Camry") 77777777777777 lereate c2 here Tested the functions in the last lab cout <<cl.getModel() << endl; Comment out this section cout <<cl.getX() <<"*«<cl.getY() << endl; return 0; 2. Make turn Left 3. Testturn Lefto using cl. If cl is facing NORTH initially, turnLeft( makes it face WEST. If el is facing EAST initially, turnleft() makes it face NORTH. Test turn Left thoroughly by calling it 4 times. 4. Now make el do the following. Wel is facing north and locating at (0,0) to begin with Go forward 3 blocks. ends up at (0, 3) Turn rights facing EAST Go forward 5 blocks. ends up at (5,3) Turn right. facing SOUTH Go forward 7 block. → ends up at (5.-4) Turn right. WEST Go forward 6 blocks. ends up at (-1,-4) Turn lett. → facing SOUTH Go forward 1 block. → ends up at (-1.-5) 5. There is an attribute called mileage, but we didn't use it in the last lab. Let's assume for each block a car goes forward, it adds one mile. Which function needs to change? 6. Show the mileage of el in main(). Do you need to add a new function to the car class? Expected output

Answer 1

Below is the code for the following question, although you did well but I have to modify and add some functionalities to make the program as required in the question.However, if you feel any doubt, please feel free to ask

Code :

#include <iostream>
#include <string.h>
using namespace std;

enum direc{NORTH, EAST, SOUTH, WEST};

class Car
{
private:
string make;
string model;
int milage;
int X;
int Y;
direc direction;
  
public:
Car(string mk, string md);

string getMake() const;
string getModel() const;
string getDirection() const;
int getX() const;
int getY() const;
int getMilage() const;

void turnRight();
void turnLeft();
void goForward(int blocks);
void setMilage(int milage);

};

//constructor
Car:: Car(string mk, string md)
{
make = mk;
model = md;
milage = 0;
X = 0;
Y = 0;
direction = NORTH;
  
}

//accessors or we can say that getter function
string Car::getMake() const
{
return make;
}
string Car::getModel() const
{
return model;
}

string Car::getDirection() const
{
switch(direction)
{
case NORTH:
return "north";
  
case EAST:
return "east";
  
case SOUTH:
return "south";

case WEST:
return "west";
}
}

int Car::getX() const
{
return X;
}

int Car::getY() const
{
return Y;
}

int Car:: getMilage() const
{
return milage;
}

//method to turn the car in right direction
void Car::turnRight()
{
if(direction==WEST)
{
direction = NORTH;
}
  
else
{
direction = (direc) (direction + 1);
}
}

// method to turn the car in left direction
void Car::turnLeft()
{
if(direction==NORTH)
{
direction = WEST;
}
  
else
{
direction = (direc) (direction - 1);
}
}

// method to move th car in forward way
void Car::goForward(int blocks)
{
if(direction == NORTH)
{
Y += blocks;
}
else if(direction == EAST)
{
X += blocks;
}
else if(direction == SOUTH)
{
Y -= blocks;
}
else
{
X -= blocks;
}
}

//setter method to set the milage of the car when car forward
void Car::setMilage(int mil_age)
{
milage += mil_age;
}

//this is our showInfo() method outside the class having the object of the car;
string showInfo(Car c)
{
string mil = to_string(c.getMilage());

string output = c.getMake() + " " + c.getModel() + " is located at ("+ to_string(c.getX()) + ","
+ to_string(c.getY()) + ") facing " + c.getDirection() + ", it has "
+ to_string(c.getMilage()) + " miles on it\n";
return output;
}

//this is the main function from where execution of program start
int main()
{
  
//object of car class c1 and c2
Car c1("Toyoto", "Camry");
Car c2("Honda", "Accord");

//creating an array which will store all forward move for the car c1
int move1[] = { 3,5,7,6,1};
string turn1[] = {"right", "right", "right", "left"};

int n1 = sizeof(move1)/sizeof(move1[0]);
int m1 = sizeof(turn1)/sizeof(turn1[0]);

for(int i=0; i<n1; i++)
{
c1.setMilage(move1[i]) ;

c1.goForward(move1[i]);

if( i <= m1)
{
if(turn1[i] == "left")
{
c1.turnLeft();
  

}
else if(turn1[i] == "right")
{
c1.turnRight();
}


}
}

//printing the details of car1 by calling showInfo() function
cout << showInfo(c1);


//creating an array which will store all forward move for the car c2
int move2[] = {5,1,2,4,10};
string turn2[] = {"left", "left", "left", "left"};

int n2 = sizeof(move2)/sizeof(move2[0]);
int m2 = sizeof(turn2)/sizeof(turn2[0]);

for(int i=0; i<n2; i++)
{
c2.setMilage(move2[i]) ;

c2.goForward(move2[i]);

if( i <= m2)
{
if(turn2[i] == "left")
{
c2.turnLeft();

}
else if(turn2[i] == "right")
{
c2.turnRight();
}

}
}

//printing the details of car2 by calling showInfo() function
cout << showInfo(c2);
  
return 0;
}

output :

Toyoto Camry is located at (-1,-5) facing south, it has 22 miles on it                                                

Honda Accord is located at (3,13) facing north, it has 22 miles on it

------------------------------------------------------------------------------------------------------------------------------------------------------------

here is the screenshots of the output of the following program :

input Toyoto Camry is located at (-1,-5)_facing south, it has 22 miles on it Honda Accord is located at (3,13) facing north, it has 22 miles on it
