can you help me with delete?

[kael6590]

I really need to finish this ASAP but with all the codes running in my head i can't think properly, I've got more system to make for finals and this one's just the 1st I hope you can help me.

i wanna ask help about delete where in when i delete empnumber the remaining emp number will go to that number for example:

I have 3 employee records


Employee records:
1 lei ren F
2 wen lei R
3 lou wuo T

: I want to delete number 2

1 lei ren F
( Deleted empoyee record Number 2)
3 lou wuo T

:now employee number 2 was delete, Instead of 2 being deleted I want number 3 to go to number 2 when deleted like so

1 lei ren F
2 lou wuo T (the previous employee records(which was employee number 2) that was deleted will be replaced by the next number 3 and the number 3 will become 2)

-------------------------------------------------
:in this code that I was able to make is if I delete employee number 2. it would look like this
1 lei ren F
( Deleted empoyee record Number 2)
3 lou wuo T

:so if i Add another entry and lets say I will use 2 again it will look like this
1 lei ren F
3 lou wuo T
2 wen lei R

here is the codes:
