This programming use basic struct - class in C/ C++ language .
Here code write object orientation , link list.....
1. Basic class: Date , Full Name , Password......................................................................
2. Struct array :sort , search , delete , display, add..............................................................
3. struct link list : sort , search , delete , display ,add .............................................................
4. Class link list: class , Node , List. add , delete.................................................................
5. Abstract : virtual function ................................................................................................
6. Template: Function-class..................................................................................................
