Operation Effect:

When the program is running, the main interface menu appears first, the user carries on the function choice, chooses the different number, enters the different function area. As shown in Figure 1.

Figure 1 Program run main interface

Select 1 to display the secondary menu and enter the employee information add interface, as shown in Figure 2.

Figure 2 Employee Information Add interface

Select Y, return to the program run the main interface, continue to select 6, then show the secondary menu, enter the staff information browsing display interface as shown in Figure 3.

Figure 3 Employee Information Display interface

To find the staff information, select 5, through the work number, name, education three ways to find, select 1 to determine according to the work number to find, as shown in Figure 4.

Figure 4 Employee Information Sorting interface

Select 4, you can sort by salary, select 1 to sort in ascending order, as shown in Figure 5.

Figure 5 Employee Information Lookup interface

Back to the program run the main interface, select 2, the staff 1 information to modify, select the secondary menu which 1~8 options to modify, as shown in Figure 6.

Figure 6 Employee Information Modification interface

Select 3 to delete the employee information, as shown in Figure 7.

Figure 7 Employee Information Deletion interface

Back to the program run the main interface, select 7, the operation of staff information to save, while returning to the main system interface, as shown in Figure 8.

Figure 8 Employee Information Saving interface
