ArrayList equivalent in C?

Hi guys,

I'm making a simple calculator program in C. It's supposed to be able to save loads of (floating point) numbers in an array and the array is supposed to expand to accommodate the new numbers. As I've been doing Java for quite some time now, I know that an ArrayList would be useful in this situation, but is there something similar to it in C?

Not that I know of. You most likely need to define your own data structure as an array list. The link here should give you some insight.

And welcome to the Ranch.

C or C++? if the latter, the vector class in the STL may help. If you are talking straight C...you may have to roll your own, as the previous poster said.

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
I agree. Here's the link: http://aspose.com/file-tools
