OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
need help woth c++.. please paste ur indeted code here
Expert Solution
CODE:
#include <iostream>
using namespace std;
//Declaring class Flight
class flight
{
public:
// Data Members
string destination;
float distance;
// Default constructor
flight()
{
destination = '\0';
distance = 0;
}
// Parameterized Constructor
flight(char c, float f)
{
char destination = c;
distance = f;
}
//Friend Function declaration
friend ostream &operator<<(istream &output, const flight &f);
friend istream &operator>>(istream &input, flight &f);
};
//overloading insertion operator
//overloading extraction operation
ostream &operator<<(ostream &output, flight &f)
{
output<< "\nDestination = " <<f.destination << "\nDistance = " <<f.distance;
return output;
}
//overloading extraction operation
istream &operator>>(istream &input, flight &f)
{
cout<<"\nEnter Destination = ";
input >> f.destination;
cout<<"\nEnter Distance (KM)= ";
input >> f.distance;
return input;
}
int main()
{
flight f1;
cout<<"\nEnter the details of flight:";
cin>>f1;
cout<<"\nEntered details are : "<<f1;
return 0;
}
