How do I exit a C subroutine

void VoidFn(int value)
{
   if (value < 0) return;
   printf("%d", value);
}

int NonVoidFn(int value)
{
   if (value >= 0) return value;
   return -value;
}

So what is the normal procedure for this type of situation. Do you normally create a pointer to the object so that you can use the new keyword to create the object?

If so, is there a way to prevent someone from creating an object and not a point to your class?

class C
{
public:
   static C* MakeNewC() { return new C; }
private:
   C()
   {
   }
};

int main()
{
   C c; // This won't compile
   C* pC = C::MakeNewC(); // This will compile
}
