Object Oriented Approach to Display a Sequence of Numbers without any for-Loop or Recursion in CPP

by

In the previous article, we have discussed about Print all Integers that Aren’t Divisible by Either 2 or 3 and Lie between 1 and 50 in C++ and Python. Let us learn About Object-Oriented Approach to Display a Sequence of Numbers without any for-Loop or Recursion in C++ Program.

Displaying a Sequence of Numbers Without any For-Loop or Recursion

In this article we will we will discuss about how to display a sequence of numbers without any For-Loop or Recursion.

Suppose we want to display from 15 to 25 without using any For-Loop or Recursion. i.e.

15, 16, 17, 18,19, 20, 21, 22, 23, 24, 25

So we will two concepts to achieve this. i.e.

  1. Constructor
  2. Static variable

C++ program to display a sequence of numbers without any For-Loop or Recursion :

// Program :

#include <iostream>

struct DisplayNumber
{
    // static member variable created i.e. Count
   static int Count;
   
   // constructore
   DisplayNumber()
   {  
      // Printing Count value
      std::cout<<Count<<std::endl;
      // incrementing the Count value
      Count++;
   }
};

// Starting value of Count
int DisplayNumber::Count = 15;

int main()
{
    // 11 objects created, so constructor will be called 10 times.
    DisplayNumber objArr[11];
    return 0;
}
Output :

15
16
17
18
19
20
21
22
23
24
25
