Print Numbers from 1 to n using class
Write a C++ Program to Print Numbers from 1 to n using class. Here’s a Simple Program to Print Numbers from 1 to n using class in C++ Programming Language.
What is Class and Objects in C++?
- Class is a user defined data type, which holds its own data members and member functions, which can be accessed and used by creating instance of that class.
- The variables inside class definition are called as data members and the functions are called member functions.
- Class is just a blue print, which declares and defines characteristics and behavior, namely data members and member functions respectively. And all objects of this class will share these characteristics and behavior.
- Objects are instances of class, which holds the data variables declared in class and the member functions work on these class objects.
- Each object has different data variables. Objects are initialized using special class functions called Constructors.
Below is the source code for C++ Program to Print Numbers from 1 to n using class which is successfully compiled and run on Windows System to produce desired output as shown below :
SOURCE CODE : :
/* C++ Program to Print Numbers from 1 to n using class */ #include<iostream> using namespace std; class Num { public: static int i; Num() { cout<<i++<<" "; } }; int Num::i=1; int main() { int n; cout<<"Enter value on n :: "; cin>>n; cout<<"\n"; Num obj[n]; cout<<"\n"; return 0; }
OUTPUT : :
/* C++ Program to Print Numbers from 1 to n using class */ Enter value on n :: 20 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Process returned 0
