In the first version of C++ Implementation of program, there In the first version of C++ Implementation of program, there are some noticeable programming algorithms and are some noticeable programming algorithms and techniques that is necessary to be introduced. They are:techniques that is necessary to be introduced. They are:

Binary SearchBinary Search played a large role in the writing the program. For example, creation played a large role in the writing the program. For example, creation of patient records, searching of a patient record through Patient’s ID of patient records, searching of a patient record through Patient’s ID and Searching the Herb’s ID. and Searching the Herb’s ID. good advantage in its running time good advantage in its running time great dependence in the order of the data structure great dependence in the order of the data structure The program has a lot of searching processes when proceeding The program has a lot of searching processes when proceeding with the above serviceswith the above servicesthe running time is greatly reduced when the number of patient the running time is greatly reduced when the number of patient records is increased records is increased

Insertion Sort.Insertion Sort. this function has played a main role in the creation and deletion of this function has played a main role in the creation and deletion of Patient Records and Herbs Records.Patient Records and Herbs Records.Insertion Sort has a great advantage in running time when the input Insertion Sort has a great advantage in running time when the input records are almost sorted. records are almost sorted.

Overloading of ConstructorsOverloading of Constructors Widely used in creating objects. Foe example: Widely used in creating objects. Foe example: the Herbs, the the Herbs, the Patient Records, the History records, etc.Patient Records, the History records, etc.reduce a lot of assignment and initialization task while there is a reduce a lot of assignment and initialization task while there is a reading of data from data files reading of data from data files It provides a convenience to programmers.It provides a convenience to programmers.

Inheritance of basic classInheritance of basic class In our program, we have created a basic class “Herbs” and two In our program, we have created a basic class “Herbs” and two inherited classes “HerbsOrder” and “HerbsInfo”inherited classes “HerbsOrder” and “HerbsInfo”They are a good example in implementation of inheritance.They are a good example in implementation of inheritance.to provide the overloading of functions from the basic class “Herb” to provide the overloading of functions from the basic class “Herb” and provides some private functions that related to the new and provides some private functions that related to the new objects. objects. everything will become very clear and easy to understand. everything will become very clear and easy to understand.
