A structure is just a grouping of items. You group them by calling them a struct <name> and surrounding them with a pare of braces:
Code:
struct yourstructname
{
    ...everything you want to group...
};
Then you simply declare one when you want to use it:
Code:
struct yourstructname yourvariablename;
To access the items you have grouped, you use the dot operator:
Code:
struct ysn yvn;
yvn.thingigrouped1 = somevalue;

someothervalue = yvn.otherthingigrouped2;
