I need help please

Write a C++ program that loops through all of the command line arguments that are passed to

the program, beginning with the argument

after

the program name.

For each argument, examine and then discard its first character. That character will tell you what

your program should do with that argument.

If the first character is the letter S, then skip the argument and print nothing for that argument.

If the first character is the letter L then convert every upper case letter in the argument to lower

case, and print the resulting argument on a line by itself. If a character is not an upper case

letter, then it should be unchanged.

If the first character is the letter U then convert every lower case letter in the argument to upper

case, and print the resulting argument on a line by itself. If a character is not a lower case letter,

then it should be unchanged.

If the first character is the letter r (lowercase r), print the letters in reverse order.

If the first character is the letter R, print the letters in reverse order while ALSO converting any

lower case letters to upper case.

If the first character is not one of the characters mentioned above, then print the word FAIL

Note that it is possible, and valid, for there to be no command line arguments after the first

command line argument.

Examples:

$ ./prog0 Smile, you people!

FAIL

FAIL

$ ./prog0 LHelp UmY34!$xxx run

help

MY34!$XXX
