Question

_{PROGRAM SHOULD BE IN C LANGUAGE...}

You are given employees database. Your code should perform the following tasks on this file.

1. Read the file.
2. Search and display the contents of file based on name, age and salary of employees.
3. Sort the data in ascending order based on the name (alphabetical order), age or salary of employees.
4. Edit the records and write the updated records back on the file.
5. The file is in text mode, the user should be able to save this file (with a different name) in the binary mode.

You have to create a proper menu driven program so that the user can select the options. You must also make separate functions for all the above-mentioned tasks.
