B.bub_sort();
B.display();

getch();
}

When I execute the code.... the value of ele is set to a junk chracter, isn't the class function supposed to manipulate the value ??

Edited 3 Years Ago by happygeek: fixed formatting

ele is never initialized. You should probably add a constructor that sets the data fields to something before working with them:

class array {
private:
  int A[20];
  int ele;

public:
  array()
  {
    for (int i = 0; i < 20. ++i)
      A[i] = 0;

    ele = 0;
  }

  void input();
  void display();
  void bub_sort();
  void insert();
  void del();
};
