Program on Show menu and calculate bill

closed account (G2zC5Di1)
Hello friends, i have got a project work on a question.
Write a program to create a restaurant menu and enter the choice of the user on the basic of choice made calculate the bill to be paid.

I have made this program but i heard it can be done with the help of arryas(i dont know about them as i have not studied) can u give me any hint on my program for making it beautiful and doing it with loops i have used only if condition i think it will be very long as i will add few more items in menu.
I have studied these things- if codition,nested if,while loop,do while loop,for loop,empty,nfinite loop,nested loops,brake statement,continue statemant,exit function.
