confusion while; break; continue.

Hello everyone, im starting with matlab, and i have a little problem if someone wants to help me it will be nice here is the problem:

A little guessing game works like this: The first player enters a number secret. The second player must guess this number. To do this, he enters a number and then the program tells him if the number to guess is greater or less than the number he suggested. he can keep entering numbers until the secret number is found. In this case, the program displays the number of tries that were required to find the secret number. If the number has not yet been found after 15 attempts, the number to guess is displayed and the program ends. Carry out this program. For interaction with the user, you can use the msgbox functions and inputdlg.

Well my code that im trying is here:

% Clean Up
% Close the opened figures and clear all variables
clear all;
close all;
% Open a dialog box asking the user 1 to put a number
secretnumber=str2double(inputdlg('Enter your secret number','secretnumber'));
%Open a dialog box asking the user 2 to put a number
number1=str2double(inputdlg('Enter your guess','number1'));
%If the number1>secretnumber show a msgbox saying it
while number1>secretnumber 
    uiwait(msgbox('Your guess is higher than the secret number, try again','modal'));
        str2double(inputdlg('Enter your guess','number1'));
        if number1<secretnumber
           uiwait(msgbox('Your guess is lower than the secret number, try again','modal'));
        str2double(inputdlg('Enter your guess','number1'));
            break
        end

end

here i am for now, i don't understand why when the value of number1 is smaller than the secretnumber; this code won't execute:

        if number1<secretnumber
           uiwait(msgbox('Your guess is lower than the secret number, try again','modal'));
        str2double(inputdlg('Enter your guess','number1'));
            break
        end

Thanks a lot, if you have any hint for the msgbox to appear when the number1 is the same as the secret number, i'm taking it thanks.

% Clean Up

% Close the opened figures and clear all variables

clear all;

close all;

% Open a dialog box asking the user 1 to put a number

secretnumber=str2double(inputdlg('Enter your secret number','secretnumber'));

%Open a dialog box asking the user 2 to put a number

number1=str2double(inputdlg('Enter your guess','number1'));

%If on the first try he got it right

if number1==secretnumber msgbox('good game 1 try')

end

%If the number1>secretnumber show a msgbox saying it

while number1~=secretnumber

% 1st time

if number1>secretnumber

uiwait(msgbox('Your guess is higher than the secret number, try again','modal'));

str2double(inputdlg('Enter your guess','number1'));

end

if number1<secretnumber

uiwait(msgbox('Your guess is lower than the secret number, try again','modal'));

str2double(inputdlg('Enter your guess','number1'));

end

end

I got until here; i don't know how to continue until 15th time, i tried to put msgbox ('you got the number after 1 try') after the last 'if' function in the loop , but whatever number i will put it will show the message box with the text inside so, what should i do to contiue until 15th times ?

Thanks a lot.

Blazhe - I think the condition on your while loop is preventing you from entering the body (of the loop) and so preventing the code from checking that the guess is less than the secret number.

while number1>secretnumber 

The above should probably be (not equal)

while number1 ~= secretnumber 

and then you would need to adjust the code within the body to ensure that you properly handle all four cases: the guess is less than the secret number, the guess is greater than the secret number, the guess is equal to the secret number, and more than 15 guesses have been made.

Thanks a lot, im trying to fix it. I changed the condition so it works now. I will try to do the other steps:

Thanks a lot for you quick response
