C++ VISUAL STUDIO

need help creating a shell program using C++

The following requirements are what I'm having the most trouble with, thank you..

c. SETTERMINATOR: sets terminator in "myshell" command prompt to inputted variable. If no terminator is defined, "myshell" should use > as the default.

d. NEWNAME: manages the alias list. The first option deletes a previously defined alias. The second optiom defines an alias for another command. Example: the command "NEWNAME mymove" deletes the alias for "mymove", the command "NEWNAME mycopy cp" defines "mycopy" at the alias for the "cp"command. If an alias for a command already exists, then the new alias replaces the old alias. The maximum number of aliases in the alias list should be set to 10 as default.

If no terminator is defined, myshe 11 should use > as the default terminator. d. (10 marks) NEWNAME I old name : Manages the alias list. The first option deletes a previously defined alias. The second option defines an alias for another command. For example, the command NEWNAME mymove deletes the alias for mymove, the command NEWNAME mycopy cp defines mycopy as the alias for the cp command. If an alias for a command already exists, then the new alias replaces the old alias. The maximum number of aliases in the alias list should be set to 10 as the default. e. (6 marks) LISTNEWNAMES: Outputs all the aliases that have been defined. Each pair of names should be shown on one line. For example, the possible aliases for a few commands are shown below: mycd cd mycopy cp f. (6 marks) SAVENEWNAMES > : Stores all currently defined aliases in the file
