simple program help, counting characters and words

[Guest_imported]

I've been trying to figure out how to write a program that takes a string input from a user and counts the number of characters and words in the string. If anyone can help me please do. I have no clue where to start. Also my IM name is hnugz2 if that's easier, thanks.

function 0Ah of interrupt 21h gets a string of chars input from a user. In the second byte of the returned string, it will give you the number of characters in the string, less the enter key.

As for the number of words, a very simple solution could be counting the number of spaces in the string and adding one. Kindof like:

You could count the spaces by going through the string character by character in a loop, doing a compare to 20h (the space character), and jumping on zero to increment a register. When you exit from the loop, add one more to the register, and you'll have the number of words.

Hope this helps.....

Presumably you want to display the number of words and characters counted too?

I bet you'll find that tougher than counting the number of words and characters... hehehe.

By the by you better make sure to check for multiple spaces, i.e.

dkil sdsd sds

has two spaces, three words

dkil   sdsd   sds

has six spaces, three words. Better filter that out too...

Look at the "hexadecimal to decimal coversion" post to get a small routine that converts an integer to a string so you can display the number of characters. And of course vote for that post...
