The problem statement is to print the numbers from 1 to 100 and then

a) recursion
b) any loops
I've coded the solution as follows:

[CODE]

#include <iostream.h>

Skip the ".h", it is pre-standard (10 years old). #include <iostream> is
the correct way, the same goes for other standard headers, not ".h" at
the end.

class list {
   private:
     static int count;
   public:
     list ()
     {
       cout << ++count << endl;

std::cout << ++count << std::endl;

or use "using namespace std;" before the class declaration.

     }
     ~list ()
     {
       cout << count-- << endl;
     }
};

You have only declared the count variable, you also need to define it:

int list::count = 0;

int main (void)
{
list a[100];
return 0;
}
