atoi array elements

[barkerben]

Hello,

I'm pretty sure of the answer to this one...

If I have an array of chars containing "123" that I want to convert to an integer value, I can use atoi.

If however I just want to process some of that array - for instance if I wanted to extract 23 - is there a way of specifying atoi to work only on certain elements of the array? I suspect I would first have to extract the desired elements into a new array, then use atoi on that...?

Cheers

Would this work?

atoi(*(&string+offset));


It might produce some ugly code though

I think that would work, if you have the \0 at the end that defines a string.

But if you have "1234\0" and try to pull out 23, you'l have problems.

I would make another array. Fill it with all \0 's and the memcpy the
charaters you want over that. That way you'll get the \0
(provided your array is +1 the max digits you'l use.
