assignment airline reservation

[shazeb asad]

i am new to programming. i was given an assignment where we had to write a code in which we had to make an airline reservation system where a user could choose from 5 options:
1.reserve a seat
2.change a seat
3.cancel a seat
4.seek help(provide roll number and name to obtain seat number)
5.exit program
The problem i am facing is that i can store the name and roll number of an individual and reserve a seat against it but when someone else enters his name and roll number it replaces the previous persons details and so when someone seeks help the program does not return the value. I tried to make a structure and pass it in an array so that each persons details gets stored in it but it did not work. Help me please.
