I don't know how to make it repeat 10 times and save all input numbers into text file in a human readable format...Can anyone help me pls?? here's my the question and my code:

Write a script, which first asks the user to input an integer number between 0 and 255, then

outputs the number to the screen between the characters '<' and '>', and calls a user function

‘mcheck’(as described below)to check the number entered. The input, display and check operation

should be repeated for 10 times. After the 10th iteration, the script should save all the input

numbers to a text file in a human readable format.

The user function ‘mcheck’ mentioned above will do the following check for each number entered:

if the number is in the range of 0 to 255, no change is needed; if the number entered is bigger

than 255, the script should print a message “error: The value too big.” to the screen, but make no

change to the value of the number; if a negative number is entered, no matter what is the exact

number, the script should convert it to -1.

I don't know how to make it repeat 10 times and save all input numbers into text file in a human readable format...Can anyone help me pls??

here's my code:

function mcheck(a)

z=input("Enter A Value Between 0 To 255 = ")

for z=z

disp("<"+z+">")

if z < 0

z = -1

elseif z > 255

disp("error: value too big")

end

end

end

K = 1:10;
for k = 1:numel(K)
    num = randi([-1 256],1); % input('Enter a number between 0 and 255:')
    disp("<"+num+">");
    Num(k) = mcheck(num);    
end
writematrix(Num,'Store_numbers.txt') % store numbers in text file 

function num = mcheck(num)
        for num=num           
           if  num < 0
               num = -1;
           elseif num > 255               
               disp("error: value too big")
           end
       end
       
end

so id I want to run this code, I will need to enter mcheck(numbers that i want to enter) right??

but why it came out as error for me??

[Muhammad Huzayl Rais]

Should I rename my file mcheck or Store_numbers

[VBBV]

No. Rename the script file in which you are running the for loop code. Save the function code mcheck in a seperate file with same name mcheck and in the same folder as the script file. Then run script file. Uncomment the first line in for loop where the user will be asked to enter a number. Delete the randi([-1 256],1). I added it to show as e.g.

What is the error you got?

[VBBV]

If you dont want numbers greater than 255 to be stored then modify code in mcheck as

function num = mcheck(num)
        for num=num           
           if  num < 0
               num = -1;
           elseif num > 255   
               num = 0;  % or NaN
               disp("error: value too big")
           end
       end
       
end

function mcheck(a)

file=[]

for n=1:10

a= input("Enter Value Between 0 To 255:")

if a<0

a=-1

elseif a>255

disp('error, the value is too big')

else

a=string(a)

file_numbers=fopen('file','w')

fprintf(file_numbers,'%s',a)

fclose(file_numbers)

end

end

file_numbers=fopen('file','r')

text=fscanf('file','%s',a)

disp(text)

fclose('file')

end

I did like this for the question above, but error occured at the fscanf part.... Can you help me rectify this problem??
