iOS Objective-C Basics (Retired) Pointers and Memory Structs

Please explain structs for me!

I don't really get the concept of structs. What's the point of having them? We made a whole bunch of variables, but didn't really do anything.

Hi Tristan,

A struct basically is a way to tie a set of related data together. for instance if I wanted a person struct I could have a char for name, an int for age and a char for job. I like to compare to compare them to classes in objective-c because they hold certain properties (or primitives because C is not object oriented) and these properties normally relevant to each other. a real world example is x and y coordinates are part of a struct, both x and y are relevant to each other so we decide to put them together in a struct.

for more info it's definitely worth googling,

Happy hacking, Kai.
