MATLAB: How to keep asking user for correct input until given

ifloop

I want a question to continue to be prompted until correct input is given. Prompt the user to input a number between 0 and 100 (inclusive) and keep prompting the user until he does so and then display the number. I am a little lost as to hopw to start it. I have this so far
    num = int(raw_input('Enter an integer between 0 and 100 '))
    if num < 0 && num > 100;
        fprintf 'Invalid input.  Try again '
    else: 
        num >= 0 && num <= 100;
        disp (num)

Best Answer

prompt = 'Enter an integer between 0 and 100: ';
x = input(prompt) ;
while x <0 || x > 100
    x = input(prompt) ;
end
