Question

What are the object oriented concepts and which all object oriented concepts are used in the
given program? Consider the following code and explain how each of the object oriented
concepts are applied in the given program. (CO1)
class Vehicle
{
string brand;
public:
void honk();
void honk(int);
};
void Vehicle::honk()
{
cout << "Tuut, tuut! \n" ;
}
void Vehicle::honk(int x)
{
for(int i=0;i<x;i++)
cout << "Tuut, tuut! \n" ;
}
int main()
{
Vehicle V1;
V1.honk();
V1.honk(3);
}

Answer 1

The object-oriented concepts available in the given program are as follows:

1. There is a clear case of inheritance. Here, Vehicle class is declared and inherited.
2. There is also a close of method overloading, where honk() method is overloaded. A method is with an integer parameter and other is without any parameter.
3. There are also concepts like Object creation. V1 is the object of the Vehicle class.

Please refer to the comments of the program for more clarity and understanding.

#include<bits/stdc++.h>
using namespace std;

/*
 Below we are creating the Vehicle class
*/
class Vehicle {
  string brand;
  /*
   Below is the condition of method overloading
   Here, honk() method is overloaded
   One method is with a integer parameter and other method is without any parameter
  */
  public: void honk();
  void honk(int);
};
void Vehicle::honk() {
    // Implementation of the honk() method without parameter
  cout << "Tuut, tuut! \n";
}
void Vehicle::honk(int x) {
    // Implementation of honk() method with a integer parameter

  // The below loop will run for x times(integer passed in the parameter)
  for (int i = 0; i < x; i++)
  cout << "Tuut, tuut! \n";
}
int main() {
  Vehicle V1;  // Creating instance of the Vehicle class.
               // Here V1 is the object of V1
  V1.honk();   // Calling the honk() method of Vehicle class
  V1.honk(3);  // Calling the honk(int) method of Vehicle class
}

Output of the above program:
