Appreciate the quick reply though.
Let me give you a few tasks that will help you experiment toward your goal as highlighted in read
Before you utilize any input validate it as something you were expecting. e.g.
How would you validate that the user have entered a proper gender? What if the user enters "Neutral" or any other variation of modern gender answers? What if it just pressed the ENTER/Return key?
How would you validate an age? What if the user enters 159 or 0 or just the ENTER/Return key?
How would you validate a name? Would you accept "Shakespeare's Hamlet" inputted as string for a name?
I have a folder with lots of file. e.g. a.txt, b.txt, c.txt.... I want to put these files from the source directory and place them in a destination directory in a specific order, such as /destination/a/a.txt, /destination/b/b.txt, /destination/c/c.txt, ......
