If saw a question in the internet which asks to write a segment code that prompt the user for a charcter and will print it twice; once left-justified in a field width of 5, and again right-justified in a field width of 3:
Here is my working:
ask=input('Enter a charcter: ','s');
fprintf('First time: %c\n',ask);
fprintf('First time:%c \n',ask);

ask=input('Enter a charcter: ','s');
fprintf('First time:%5c\n',ask);
fprintf('Second time:%0.3c\n',ask);
I think that the first one is correct but the second fprintf is not.

Neither one are correct. Your first one does not left justify and the right one does not print the character.
