Can you Help me About This Machine Problem in C

[renren00]

This is the machine problem.

Write a program that will identify word that the user inputs and determine how many times that word uses the certain letters, that the word contains. The program must not accept a numeric value and special characters except the "-" that is needed in compound words as input . And the letters will be in alphabetical order.

Example :

I enter the word "letters"

The program must show:

e = twice
l = once
r = once
s = once
t = twice

If I enter the word "add5@6" with number or special character in the input word
the program will say "Wrong input" and will require the user to input another word.



I would appreciate your help guys. comment your program here or send it to my e-mail [e-mail]

You wish.
As for the problem, sorting the string would make it trivial. You'd only need one pass through it to count all characters.

Well, I think you need to use arrays with strings.
