// C++ program to How will you print  

//  numbers from 1 to 100 without using loop?  

#include <iostream>  

using namespace std;  

 

class gfg  

{  

     

// Prints numbers from 1 to n  

public:  

void printNos(unsigned int n)  

{  

   if(n > 0)  

   {  

       printNos(n - 1);  

       cout << n << " ";  

   }  

   return;  

}  

};  

 

// Driver code  

int main()  

{  

   gfg g;  

   g.printNos(100);  

   return 0;  

}
