description------------------------------------------------------------------------------------
1. statement prints the string (nothing special happens.)
2.statement prints the string, but print 15 characters. If the string is smaller the “empty” positions will be filled with “Space.”
3. statement prints the string, but print only 10 characters of the string.
4. statement prints the string, but prints at least 10 characters. If the string is smaller “space” is added at the end. (See next example.)
5. statement prints the string, but prints at least 15 characters. The string in this case is shorter than the defined 15 character, thus “space” is added at the end (defined by the minus sign.)
6. statement prints the string, but print only 15 characters of the string. In this case the string is shorter than 15, thus the whole string is printed.
7. statement prints the string, but print 15 characters.
If the string is smaller the “empty” positions will be filled with “space.” But it will only print a maximum of 10 characters, thus only part of new string (old string plus the space positions) is printed.
8. statement prints the string, but it does the exact same thing as the previous statement, accept the “space” is added at the end.
