How do I use input to make a string and fprintf to output different parts of the string?

I'm trying to write a program that will allow the user to enter their name as a string. And then using fprintf, output the user’s name as well as the first and last letter of the users name separately.

name=input('enter your name ') say you input brian, I want the output to be "brian" , "b" , "n" all separate

The portion of the input should work fine (EDIT: Nvm, listen to James answer). If you want just first and last letters then you should be able to save them as different values using indexing.
name = input('Enter your name: ');
first = name(1);
last = name(end);
fprintf('Your name is: %s %nWith first and last letters: %c and %c%n',name,first,last);
The exact syntax may be a bit off since I don't always remember the exact nuances of fprintf, but that should be pretty much what you want.

Use the 's' option to read the input as a string. E.g.,
name=input('enter your name ','s');
Then you can use fprintf with three different %s formats to print out name, name(1), and name(end).
