    //this character array (my_string) is 12 characters long
    //"hello" is 5 characters, " " (the space) is 1 character
    //"world" is 5 characters. 5+1+5=11, not 12, so where is the last character?
    //the last character is a 0 (or "\0") automatically added at the end of the character array
    //I will now print out the string with it's corresponding ascii value http://www.asciitable.com/index/asciifull.gif

    //because of the fact that there is a 0 at the end of every string, you don't have to worry about the length of the string
    //this time I will print out characters until I hit the "\0" at the end, (because that is the end of the string)
