Structures

• Structures are a mechanism to better organize data
• The “struct” syntax, struct { member, member, etc. };
• Some examples using structures are presented, such as a “person” with a name and an age
• Members of a structure variable are accessed using the dot (.) operator, e.g. var.member
• Structures can contain members that are themselves structures
• Structures can be initialized at compile time, or at run-time
• Structures can be organized in arrays
• Even multi-dimensional arrays
• Pointers can point to a structure,
• This allows for run-time allocation and de-allocation of structures
• This is also the only way a structure may have itself as a member
• Members of a structure pointer are accessed using the (–>) operator, e.g. ptr–>member
