% the script asks for and adds book to the library
A=input('What would you like to do?: ','s'); %promots the user
while strcmp(A,'add book')==1 %if 'A'is add book the computer will ask for details
Tit= input('Ask for title: ','s');
Aut=input('Ask for author: ','s');
No_pg=input('Ask for number of pages: ','s');
fprintf('%s,%s,%s have been added to the library \n',Tit, Aut, No_pg)
Ve=[Tit:Aut:No_pg];
A=input('What would you like to do?: ','s');% will keep asking until prompt is different
if strcmp(A,'list book')==1
fprintf('Title: %s \n',Tit)
fprintf('Author: %s \n',Aut)
fprintf('Number of pages: %s \n',No_pg)
elseif strcmp(A,'quit')==1
disp('Good bye')
else
disp('Invalid Input')
end
end
In this script If i prompt 'add book'in A it asks for title, author, number of pages of the book. If i prompt 'quit'it displays goodbye and that is the only two strings for now. I want the code to keep asking 'What would you like to do'and I keep 'add book' to it and after a while i prompt 'list book' which should list all the books I have types. So far I can only do one. Example if i prompt 'add book' and have title= Harry potter author =jk rowling no. of pages=132 and i keep adding books and after a while I prompt list book the code only displays the last book i added and not all of them

index = index + 1;
Tit{index} = input('Ask for title: ','s');
Aut{index} = input('Ask for author: ','s');
...
for J = 1 : index
fprintf('Title: %s \n',Tit{J})
fprintf('Author: %s \n',Aut{J})
...
end
