We implemented a simple program for a supervisor who is in charge of up to 5 employees. The program can read timesheet from a given .txt file in a certain format.The supervisor can access information of employees, approve/disapprove any employee's timesheet card, and make changes to the timesheet. The I/O of the program is realized in a style of command line, with a console UI. This program is implemented in C++ with basic data structures and OOP design.
