Question

MATLAB HW 11 problem using Switch Case and Input commands

Write a script file that calculates the cost of a movie tickets according to the following price schedule:

                                                 Number of Tickets being purchased

Time of Movie	< =5 tickets	6 to 9 tickets	>=10 tickets
Afternoon	$6	$30 + $5 for the number of tickets above 5	$50 + $4 for the number of tickets above 9
Weeknight	$7	$35 + $6 for the number of tickets above 5	$59 + $5 for each ticket above 9
Weekend	$9	$45 + $8 for the number of tickets above 5	$77 + $7 for every ticket above 9

1) The program MUST use Switch Case and Input commands for full credit.

2) The program must ask the user to input if the movie is Afternoon, Weeknight or Weekend. It should contain a safeguard that tells the operator if they have not correctly identified the time of the movie.

3) The program must ask the operator the number of tickets to purchase.

4)   The program must make the operator’s response lower case. For example if Time={‘AFTERNOON’} your program should contain something like

Time2=lower(Time) which converts the ‘AFTERNOON’ string to ‘afternoon’ to use in switch case so that no errors in capital letters vs. lower case letters can be made.

5) Show the cost of the movie tickets, the number purchased and for what time using an fprintf statement.

6) Test your program to see if it runs. Be prepared to demonstrate to the instructor how the program operates if requested by the instructor.

7) Submit a copy of the script file cut and pasted into Microsoft Word. Submit the assignment over Blackboard. (Remember that the Publish option under MATLAB is not compatible with input commands. )

Answer 1

The MATLAB Code is as follows:

clc
clear all

time=input("Enter the time of the movie (Afternoon, Weeknight, Weekend): ",'s'); %Read the time for movie
time2=lower(time); %convert the time to lowercase
while ~(strcmp(time2,'afternoon') || strcmp(time2,'weeknight') || strcmp(time2,'weekend'))
%if the time enetered is neither afternoon, weeknight nor weekend, then
%print error message and read the input again until valid input is entered
    fprintf("Invalid Input\n");
    time=input("Enter the time of the movie (Afternoon, Weeknight, Weekend): ",'s');
    time2=lower(time);
end
tickets=input("Enter the number of tickets to be purchased: "); %read the no.of tickets
switch time2 % use switch case on timeX of the movie
    case 'afternoon' % case afternoon
        if tickets<=5 % if no.of tickets is less than ir equal to 5, then amount is $6
            amount=6;
        elseif tickets>=10 % if no.of tickets is greater than or equal to 10, then amount is $50+$4 for no.of tickets more than 9
            amount=50;%initial amount
            inc=tickets-9; % No.of tickets more than 9
            amount=amount+inc*4; % final amount=main amount + additional amount
        else % if both conditions are not satisfied, then No.of tickets will be in the range of 6-9
            amount=30; %initial amount
            inc=tickets-5; % No.of tickets more than 5
            amount=amount+inc*5; % final amount=main amount + additional amount
        end
    case 'weeknight' % case afternoon
        if tickets<=5 % if no.of tickets is less than ir equal to 5, then amount is $7
            amount=7;
        elseif tickets>=10 % if no.of tickets is greater than or equal to 10, then amount is $59+$5 for no.of tickets more than 9
            amount=59; %initial amount
            inc=tickets-9; % No.of tickets more than 9
            amount=amount+inc*5;% final amount=main amount + additional amount
        else
            amount=35; %initial amount
            inc=tickets-5;% No.of tickets more than 5
            amount=amount+inc*6; % final amount=main amount + additional amount
        end
    case 'weekend' % case afternoon
        if tickets<=5 % if no.of tickets is less than ir equal to 5, then amount is $9
            amount=9;
        elseif tickets>=10 % if no.of tickets is greater than or equal to 10, then amount is $77+$7 for no.of tickets more than 9
            amount=77; %initial amount
            inc=tickets-9; % No.of tickets more than 9
            amount=amount+inc*7; % final amount=main amount + additional amount
        else
            amount=45; %initial amount
            inc=tickets-5; % No.of tickets more than 5
            amount=amount+inc*8; % final amount=main amount + additional amount
        end  
end
fprintf('\n******** BILLING DETAILS ********\n');
fprintf('The time of the show: %s\n', upper(time2));
fprintf('Number of tickets purchased: %d\n', tickets);
fprintf('The total amount of tickets: $%d\n', amount);

OUTPUT:
