I have been told to make a script that will evaluate a string, and at the end it must ask the user if they are sure they want to quit if yes then quit if no then rerun the switch.
this is an example of what i need it to look like for choice 7:
Please choose an option:
1. Length
2. First letter
3. Last letter
4. Reverse
5. All
6. Enter a new string
7. Quit
Choice: 7
Are you sure you would like to quit (Yes/No)? n
Please choose an option:
1. Length
2. First letter
3. Last letter
4. Reverse
5. All
6. Enter a new string
7. Quit
Choice: 7
Are you sure you would like to quit (Yes/No)? y
Quitting program

my code looks like:
clear; clc; close all;
choice = input('please give a "string"(PHRASE) to be evaluated: ', 's');
%this is a function that i created that evaluates the string.
[length firstLetter lastLetter reverse all] = singletary6(choice);
%function [stringLength, firstLetter, lastLetter, reverse, all] = singletary6(str)
%if isempty(str)
% stringLength = 0;
% firstLetter = '';
% lastLetter = '';
% reverse = '';
% all = '';
%else ~isempty(str);
% stringLength = length(str);
% firstLetter = str(1);
% lastLetter = str(length(str));
% reverse = str(end:-1:1);
% all = str;
%end
%end
disp(choice)
menu = sprintf('1. length\n2. First letter\n3. Last Letter\n4. Reverse\n5. All\n6. Enter a new String\n7. Quit\n');
fprintf('1. length\n2. First letter\n3. Last Letter\n4. Reverse\n5. All\n6. Enter a new String\n7. Quit\n');
choose = input('Choose a comand from 1-7:');
while choose <= 7
switch choose
case 1
length
disp(menu)
choose = input('Choose a comand from 1-7:');
case 2
firstLetter
disp(menu)
choose = input('Choose a comand from 1-7:');
case 3
lastLetter
disp(menu)
choose = input('Choose a comand from 1-7:');
case 4
reverse
disp(menu)
choose = input('Choose a comand from 1-7:');
case 5
all
disp(menu)
choose = input('Choose a comand from 1-7:');
case 6
choice = input('Enter a new String(phrase)', 's');
[length firstLetter lastLetter reverse all] = singletary6(choice);
fprintf('\n')
disp(menu)
choose = input('Choose a comand from 1-7:');
fprintf('\n')
case 7
disp('Quit')
button = sprintf('Ready to quit?\nYes\nNo\n');
switch button
case 'Yes',
disp('Exiting MATLAB');
save
case 'No',
quit cancel;
end
end
end
