Write a c++ program that inputs (at most 50) records from a sequential file.

Use the following structure definition in your program.

Write a c++ program to insert the records into an ordered (maintain order at all times) array (max 50 records)(ordered by Last_name in alphabetical order). Then print the records in ordered by last name. Years if service 0 5 4.5% (based on annual salary) , 6 10 12.5% 11- 15 30.85% 16 20 45.9% over 20 65.90% annual retirement salary. Department codes AC accounting MD medical EG engineering TE technical PP -physical plant ST staff LW legal Rd research TT testing QC -quality control.

Validate the data in each record before storing it in the data structure, any record found to be in error should be written to an

to a file called "error.dat" along with the reason for the error.
