Hello everybody, I have a question for while loop on C#

[slaskdkasdasd]

Print the decimal, octal, and hexadecimal values of all characters between the start and stop characters entered by a user. For example, if the user enters an a and a z, the program should print all the characters between a and z and their respective numerical values. Make sure that the second character entered by the user occurs later in the alphabet than the first character. If it does not, write a loop that repeatedly asks the user for a valid second character until one is entered. Your output should be formatted as shown below

Letter           Decimal                Octal      Hex

a                              97           141         61

b                             98           142         62

c                              99           143         63

d                             100         144         64

e                             101         145         65

Thanks...
