CSIT Object Oriented Programming With C++ (Overloading Comparison Operator)

 In this post, I will teach you to overload Comparison operator.

Comparison operator are used to compare two values and its result is always true or false. So operator function must return an integer value 1(if true) or 0 (if false).

We can overload greater than operator(>) as follows.


//Overloading comparison (greater than) operator
#include<iostream>
using namespace std;
class Distance
{
int feet,inch;
public:
void getdata()
{
cout<<"Enter Distance: ";  //feet first then inch
cin>>feet>>inch;
}
int operator > (Distance d)
{
int fd,sd;//first distance and second distance
fd=feet*12+inch;
sd=d.feet*12+d.inch;

if(fd>sd)
return 1;
else
return 0;
}
};

int main()
{
Distance d1,d2;
d1.getdata();
d2.getdata();
if(d1>d2)
cout<<"d1 is greater than d2"<<endl;
else
cout<<"d2 is greater than d1"<<endl;
return 0;
}

In this way we can overload Comparison( greater than) operator.
We can also do it in same ways for other  comparison 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++(Insertion and Extraction Operator Overloading ) Part VI

  I am assuming that, You have already studied previous parts of Operator Overloading Series. So i n 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 ...

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(...
