1. Draw a flowchart for the following code

2.- Use parts of the codes to guide your explanation in describing all the user options in the program. Include all the requirements (a small part of the codes and explain) and how you code your program. check the code and explain whichever the following requirements presented in the code:

Add data

View all data

Search a particular data

Delete a particular data

Check valid and invalid input

Usage of selection and repetition (where appropriate) structures

Usage of methods

Usage of array

Usage of menu

Some forms of calculation
