 Assembly does not support any aggregate types (such as arrays, structs, etc) natively. You can however (obviously) make your own.
 In the following section we will cover how \lC\ datatypes are compiled into assembly.
+Do note that the \texttt{sizeof} function in \lC\ returns the number of bytes.

 Another issue is accessing members. The solution to this is however easy and efficient, as at compile time, the offsets are pre-determined
 and compiled into the setter and/or getter code for the struct.
