C++ program to print 1 to N numbers without a loop

C++ program to print 1 to N numbers without a loop



I remember the day when i was asked about this question of printing 1 to N numbers without using a loop or a condition or something else by my senior. At that time the only thing that came to my mind is Recursion. But after knowing some concepts of Object Oriented Programming, I nodded that yes, it is indeed possible.


You remember the static data type in C++ ?
Yes, it maintains a single copy for the whole class created.
By now many of you might have got the Idea? Here's the Simple C++ code to do this.



#include <iostream>
using namespace std;
class increment
{
static int foo;
public:
increment
()
{
foo
++;
cout
<<foo<<endl;
}
};




int increment::foo=0; //Initializing static data type.




int main(void)
{
increment buff
[10]; //constructor called 10 times.
return (0);
}

Here's the Sample output:
