Homework SourseWrite a C program to manage a parking lot Build Specificatio
Write a C++ program to manage a parking lot.
Build Specifications:
1. The parking lot has multiple levels. Each level has multiple rows of spots.
2. The parking lot can park motorcycles, cars, and buses.
3. The parking lot has motorcycle spots, compact spots, and large spots.
4. A motorcycle can park in any spot.
5. A car can park in either a single compact spot or a single large spot.
6. A bus can park in five large spots that are consecutive and within the same row. It cannot park in small spots.
Function description:
1. Setup the parking lot. You should be able to create a customizable parking lot.
2. Edit the parking lot layout: You should be able to change the parking lot layout. For example: Add levels, change the spot layout at a level, etc.
3. Reserve: You need to be able to reserve a spot. The user should provide the level number, the row number, and then the spot number.
4. Search: See how many free spots on a specific level.
5. Get Free spots: How to get how many free spots of each kind in the whole parking lot.
6. View: View all levels and their information
The program must have the following properties: - You should do error handling (Ex: you cannot choose a level that does not exist) - You should use inheritance, polymorphism, and aggregation. Example: You can design a generic spot class, then design derived classes for different kinds of spots.
Also, design a menu (should still appear until the exit option is chosen) in the Main program that has the following options implemented to test your classes’ functionality:
1. Setup the parking lot
2. Edit
3. Look for capacity
4. View level information
5. Exit
I\'ve gotten this far in the code, but I\'m stuck. Any help would be appreciated.
#include <iostream>
#include <string>
#include <vector>
using namespace std;
class Vehicle
{
public:
int VehicleID; // ID for each vehicle
char vehicleType;//char VehicleType; //M for motorcycle, B for Bus, C for Car
int numberOfrowsOccupied;
Vehicle(int id, char type, int numRowsOccupied)
{
VehicleID = id;
vehicleType = type;
numberOfrowsOccupied = numRowsOccupied;
}
};
class Level
{
public:
int levelNumber;
int numberOfRows;
vector<Vehicle> vehicles;
Level(int lNumber, int numRows)
{
levelNumber = lNumber;
numberOfRows = numRows;
}
void addVehicle(Vehicle veh)
{
vehicles.push_back(veh);
}
void removeVehicle(int id)
{
for(std::vector<Vehicle>::iterator it = vehicles.begin(); it != vehicles.end(); ++it) {
Vehicle veh = *it;
if(veh.VehicleID == id)
{
vehicles.erase(std::remove(vehicles.begin(), vehicles.end(), veh), vehicles.end());
break;
}
}
}
};
class ParkingLot
{
public:
int numberOfLevels;
vector<Level> levels;
ParkingLot(int numLevels)
{
numberOfLevels = numLevels;
}
void addLevel(Level lev)
{
levels.push_back(lev);
}
};
int main()
{
}
Solution
Answer: See the code for main function below. Also note the inline comments.
----------------------------------------------------------
//main function
int main() {
ParkingLot *parkinglot;
//loop to display menu and process user input
int choice; //choice of user
while(1)

fflush(stdout);

Level level(level_no,num_rows); //create new level
parkinglot->addLevel(level);
cout<<\"Level added.\"<<endl;
}
//you can add other edit functionality here also as required.
break;
case 3:
cout<<\"Look for capacity:\"<<endl;
cout<<\"Level-wise number of free spots are as below:\"<<endl;

cout<<\"Information about level \"<<level_no<<\":\"<<endl;
cout<<\"Number of rows:\"<<parkinglot->getLevels().at(level_no).getNumberOfRows()<<endl;
//display other information here.
break;
case 5:

exit(1);

cout<<\"Wrong choice! Re-enter.\"<<endl;
