Hey everyone, just wondering how I could restrict certain user inputs. I want my program to accept two inputs, in this case being 'i' and 'm' and if the user were to enter a number or a different string, my script would keep looping the input question until the user enters the correct value. (Essentialy I just need help on where I commented)
y = input('Please enter the letter ''i'' for an imperial output or ''m'' for a metric output: ', 's');
while isempty(y)
disp('Blank is an invalid input you are required to enter a number from the options above!')
y = input('Please enter the letter ''i'' for an imperial output or ''m'' for a metric output: ', 's');
end
while
disp(' Invalid input,please enter the letter ''i'' for an imperial output or ''m'' for a metric output')
y = input('Please enter the letter ''i'' for an imperial output or ''m'' for a metric output: ', 's');
while isempty(y)
disp('Blank is an invalid input you are required to enter the letter ''i'' for an imperial output or ''m'' for a metric output!')
y = input('Please enter the letter ''i'' for an imperial output or ''m'' for a metric output: ', 's');
end
end
switch y
case 'i'
fahrenheit = (z*9/5)+32
case 'm'
celsius = (z-32)*5/9
end
