Kindly to change the code below to make it user interface code instead of display code as follow

The main program will run to show below display

1. Add supplier

2. Add Manpower

3. Display All expenses

4. Exit

If you chose 1 then will let you pick one of the three suppliers in the system

If you chose 2 then it will show you to add the name , ID, designation , hourly pay , weekly worked hour, overtime

If you chose display all expenses the program will show you all data you entered ?

The answer should be full code
