Object Oriented Approach to Display a sequence of numbers without any For-Loop or Recursion

Suppose we have to display a sequence of numbers like from 10 to 20 i.e.

10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20

without using any for-loop and recursion.


We will use two concepts here,

  • Constructor
  • Static Variable

[showads ad=inside_post]

Create a Structure with a static member variable i.e. a Counter. Then in this structure’s constructor display the Counter and increment it.


struct NumberGenerator
   static int mCounter;

int NumberGenerator::mCounter = 10;

Now in the main function just Create 11 Objects of this Structure and hence constructor will be called 10 times.
Inside each constructor call, a static counter will be printed and its value will be incremented.

int main()
    NumberGenerator objArr[11];
    return 0;

Thus a sequence of integers will be printed.
