help with c++ menu

hey guys here is my program
http://pastebin.com/R6cN7jQb

ive already been told how poorly presented my code is, i will try and fix it later.
it runs, with 2 problems

in option6 it asks me to cin a name but everytime i put a space in the string it stops working.
i need to know how to add spaces to the string input

also in option 7, i am trying to delete a tuple but the program closes when i enter the studentID

any thoughts?

cin
scanf or GTFO
