I am able to type the name and age for 4 people. For numbers greater than 4(for ex: for 5 tickets, 6tickets,etc.) I do not get any displays but I can type. Please help me to rectify the display. Thanks.

The problem is that you've only allocated space for 2 passengers. Change line 6 to have the maximum number that you expect. Alternatively, allocate the passenger array on the heap after the user enters the number at line 11.
