Hello folks,
First timer here so bear with me. I'm trying to tokenize an array of strings.
This program reads an array of strings, each string has a First and Last Name and some have Middle Names. The array of strings is then bubble sorted(not the most efficient but required)
The problem im having is this:
I'm trying to
strcpy(MiddleName[a],tokenPtr) if there is a Middle Name
otherwise Middle name returns a Null
strcpy(LastName[g],tokenPtr)
as you can see, I am tokenizing each string and successfully managed to get the FirstName array. I am having problems with the rest using strtok...primarily crashing the programing.
I'm not sure how to code the following(assuming it is correct)
if there is nothing else to tokenize(two name string), dont tokenize it
tokenize the rest of the elements(3 name string)
I think im confusing myself
**Note: The spaces between names are purposely there

}Thanks folks
No more coffee for me... :eek:
