  • Hey this code is not correct.
    While entering password,
    if you press ENTER key also it is printing *.
    if you press BACKSPACE or DELETE or ESC or anything, it is printing *.

    Your code will be valid only if you fix this validations.

    First off I want to say terrific blog! I had a quick question that
    I’d like to ask if you don’t mind. I was interested to know how you center yourself and clear your
    head prior to writing. I have had difficulty clearing my thoughts in getting my ideas out.
    I do take pleasure in writing but it just seems
    like the first 10 to 15 minutes are lost simply just trying to figure out how to begin. Any suggestions
    or hints? Cheers!
