<(first_name.last_name.) Something like that>well, from the example you gave there, i think the way you use structure is pretty similar to C++.
the way we do in C++ is:
struct//this is the keyword for using struct// name//name for the struct
{
int var;
char[12];
so on....
};
name names//names is pointed to the structure name... in here, name works like a data type (ie. int,float)
names.var=12;
//this is using the pointer (names) you just declared to access to the member (stuff inside the structure), in the above statment, you just initialized that the variable var equal to the value 12. the dot (.) is use to access to any members(all the variables inside the structure)
that's the basic idea about structure
hope it helps 😉
