Keyboard Inputs in MATLAB 2015a Version

Question

Hi!

I'm trying to do the following using MATLAB 2015a version

Add a keyboard input for a user to input any number and displays it as follows:

The code I wrote is as follows:

x=input('Enter a number: ');

printf(Entered number is: ', x);

And an error is displayed as below regarding the 2nd code line

Undefined function 'printf' for input arguments of type 'char'.

How can I correct this?

Answer 1

The error indicates you're collecting the incorrect data type from your input (char) and then using it as an argument for an invalid function. The mistake here is in your print statement; I expect the function you actually wanted was fprintf, like this:

x = input('Enter a number.');

x = str2double(x);

fprintf('Entered number is %d\n',x);
