Help me with split function.

I have an CHAR array, in that array, each "place" has this syntax: "xxx-yyy"

Where XXX is a Id value and YYY is a property.

I want to make a function that goes to a "place" in that array, for example array[2], and receives something like this "437-662", and splits it into 2 int variables, the result may be like this:

CHAR id = 437 and CHAR prop = 662.

How can i do that?

(no, i cant use struct or something....)

You can use modulus division to separate everything less than 1000 and > 1000.

int n = 437662 ;
int prop = n % 1000 ;
int id = n - prop ;

hmmm very interesting solution.

thanks,


may i have more possible solutions, i'l learning C, so the more the better i learn ;)

you can use strchr to find a '-' location and strncpy to copy part of the string

You could convert the int to a 6 byte string, then memcpy() the first 3 characters into a new array, then strcat() a '-', then strcat() the last 3 characters.

The OP said he had an int array, but used an example of a string to show what he was storing. So, either he doesn't have an int array and is using a char array, in which your solution will work, or, he does have an int array and the values are encoded like I proposed.

What I see - It is the talking about CHAR array

He (she) edited it. It used to say int array, and the variables were all ints.

And for not apologizing for to me for me wasting my time, or posting to say he was mistaken when editing it, I banish him (her) to the no-response-from-me-for-now-on-queue.

sorry man, but when i edited it was because i though that it was wrong. At the begining i was doing with INT, and now i'm still using INT, I was going to use char after all but after i saw your post, that you made some seconds before i edit the post, i leave has it was, in INT.

But after that i let the edited post with CHAR because i wanted to see how i could do it with chars to so you'r post wasn't a waste of time.

Thanks everyone! ;)

Thank you.
