CSIT Object Oriented Programming with C++(Insertion and Extraction Operator Overloading ) Part VI

 I am assuming that, You have already studied previous parts of Operator Overloading Series. So in this post, I am going to teach you How to Overload Insertion and Extraction operator.

Here, I will overload '<<' and '>>' operator to input and output  distance class data. 

So, let's get started,


#include<iostream>

using namespace std;

class Distance{

int feet,inch;

public:

Distance(){

feet=0;inch=0;

}

Distance(int f,int i){

feet=f;inch=i;

}

friend ostream &operator <<(ostream &output , const Distance &d)

{

output<<"Feet: "<<d.feet<<" Inch: "<<d.inch<<endl;

return output;

}

friend istream &operator >>(istream &input, Distance& d)

{

input>>d.feet>>d.inch;

return input;

}

};

int main()

{

Distance d1(4,8), d2;

cin>>d2;

cout<<d1<<endl;

cout<<d2;

return 0;

}


In this way we can overload insertion and extraction operator.

CSIT Object Oriented Programming with C++(Unary Operator Overloading using Friend function) Part IV

  I am assuming that, You have already studied Part I,II and III of Operator Overloading Series. So i n this post, I am going to teach you How to perform Unary operator overloading using friend function. So, let's get started, //Overloading pre-increment operator using friend function #include<iostream> class A{ int length,breadth; public: A(int l, int b) { length=l; breadth=b; } friend void operator ++( A&); void display() { cout<<"Length: "<<length<<endl<<"Breadth: "<<breadth<<endl; } }; void operator ++( A& b); { ++b.length; ++b.breadth; } int main() { A a(7,14); ++a;     //equivalent to operator ++(a); a.display(); return 0; } OUTPUT Length: 8 Breadth: 15 This is for pre-increment operator. In next post, I will teach you overloading binary operator using member function.  So refer next  post for that topic.

CSIT Object Oriented Programming with C++(Unary Operator Overloading) Part III

  I am assuming that, You have already studied Part I and II of Operator Overloading Series. So i n this post, I am going to teach you How to do Unary  operator Overloading . Before we get started towards our topic, I wanted to remind you, what  Unary Operator Really is? An operator which acts upon only one operator is called unary operator. For example: Increment operator, Decrement operator and Negation operator (Minus) which  acts as both unary as well as binary operator. Now, lets do coding to understand , how to perform unary operator overloading. Here, I will do Pre-Increment operator overloading. Have a look at this simple code and understand the basic. //Overloading pre-increment operator #include<iostream> class A{ int length,breadth; public: A(int l, int b) { length=l; breadth=b; } void operator ++() { ++length; ++breadth; } void display() { cout<<"Length: "<<length<<endl<<"Breadth: "<<breadth<<endl; } }; int main(...
