@Naziya-Parveen All these should be in a single file and user can perform crud for terminal itself. The program must be menu driven.

Please check it now.

@Naziya-Parveen 'clear' is not recognized as an internal or external command, operable program or batch file. Warning during exec. Also consider renaming of the main file.

[Naziya-Parveen]

It's working perfectly fine. You can replace 'clear' with 'cls' if 'clear' is not supported.
