The point of a structure is to keep a common set of variables grouped together. For instance you could create a structure for a robot's arm, with a variable for the motor and the sensor monitoring the angle.

One concept of "good programming technique" is to keep the variable's scope so that only functions that require access to it are able to. Structures are variables and this rule applies. In general you want to try to keep as few globals as possible. Instead, declare a variable static in a function; that will keep the value of the variable after it is removed from the stack (gone to a different function.)
