Bugs :
1. Problems handling names cause all names scanned includes space at the end(e.g. "Herman Cruz" becomes "Herman Cruz ") making the "View" buggy. Lets say you have 3 records, the view gives me result of 6 records isntead of 3. those extra 3 records have no name. Delte is also bug upon search the name to delete, im forced to include space after the name in order to match the stored name in the data. Same goes for EDIT and search.
2. Cant implement the pause ability in View wherein elts say theres 20 person wherein I can pause for every 3 names then clearscreen.
3. Handle empty records and no search result.
Pls guys I need help. Its my thesis that needs to be defended tomorrow. Its a defense.
