Factorial Program using classes C++
Classes are basically created to compress a big program into a small program that is meaningful too. Here , we gonna work on a factorial program using classes. #include<iostream.h> #include<conio.h> class factorial { int i,f,num; public: void read(); void fact(); void display(); }; void factorial::read() { cout<<"Enter an Integer to get Factorial:- "; cin>>num; } void factorial::fact() { f=1; for(i=1;i<=num;i++) { f=f*i; } } void factorial::display() { cout<<"Factorial of "<<num<<" :-"<<f; } void main() { factorial vk; clrscr(); vk.read(); vk.fact(); vk.display(); getch(); }
Operator overloading in C++ (Cout and Cin)
#include<iostream.h> #include<conio.h> class distance { int feet,inches; public: distance() { } distance(int f,int i) { feet=f; inches=i; } friend ostream &operator<<(ostream &output,const distance &d) { output<<"F: "<<d.feet<<" I: "<<d.inches; return output; } friend istream &operator>>(istream &input, distance &d) { input>>d.feet>>d.inches; return input; } }; void main() { distance d1(11,10),d2(5,11),d3; clrscr(); cout<<"Enter the value of object: "<<endl; cin>>d3; cout<<"First Distance: "<<d1<<endl; cout<<"Second Distance: "<<d2<<endl; cout<<"Third Distance: "<<d3; getch(); }
