Hello guys! im a newbie in programming and i need help..Anyone familiar with array??below is the case and i hope someone can help me.. thx..

Write a program to assign seats on each flight of the airline’s only plane (capacity: 20 seats). Your program should display the following menu of alternatives: Please type 1 for "Business" and Please type 2 for "Economy". If the person types 1, your program should assign a seat in the first-class section (seats 1–10). If the person types 2, your program should assign a seat in the economy section (seats 11–20). Your program should print a boarding pass indicating the person’s seat number and whether it is in the first-class or economy section of the plane.

Use a one-dimensional array to represent the seating chart of the plane. Initialize all the elements of the array to 0 to indicate that all seats are empty. As each seat is assigned, set the corresponding elements of the array to 1 to indicate that the seat is no longer available.

Your program should never assign a seat that has already been assigned.

Well, start coding. If you have a problem post again, with your code and a description of your problem, along with any error messages (complete) and we will help, but we are not going to write it for you.

Hi again..this is what i do so far..
but there is still a problem, bcos my teacher told me that the seats must be randomly assigned..So for example, user choose Business, then the seats go random between 1 to 5..
