Iterative Data

Example Written in C++
Demonstrates how NOT to handle iterative data as well 
as a few other general DO-NOT's


using namespace std;

class Person
   //Our encapsulated data
   string Name;
   int Age;

   //Default constructor
   Person() : Name(""), Age(0) {};
   Person(string _Name, int _Age) : Name(_Name), Age(_Age) {};

   //Mutator functions allow modification of data
   void SetName(string _Name)
     Name = _Name;
    void SetAge(int _Age)
     Age = _Age;

    //Accessor funtions allow access to data value
    string GetName()
     return Name;
    int GetAge()
     return Age;
int main()
  //Create an Array of 3 Persons, 
  //This is BAD! You should not use a constant number for the size
  Person People[3];

  //This is the BAD way, iterative data should use a loop here
  People[0] = Person("", 0);
  People[1] = Person("", 0);
  People[2] = Person("", 0);

  //Loop used but still using literal and using <= shows you might not know 
  // for sure what's happeneing 
  for (int i=0; i <=2; i++) 
    People[i].SetAge((i + 1) * 9); 
  //Still using literals, loop is properly used, but should have { } to encampsulate the i 
  while (i < 3) 
    cout << People[i].GetName().data() << " is " << People[i].GetAge() << " years old." << endl; 
  return 0;
