Using Structs

General Programming → Programming Tips Tricks → Using Structs

Structs are variables made of a collection of other variables. Again, this is not unique to ROBOTC, but still useful in general, and not as widely known to beginning programmers. I'll demonstrate with an example:

typedef struct{ int maxPos; int minPos; int armSpeed; int prevSensorValues[10]; } robotArm;

This is an example of a struct. If you have multiple arms on your robot, you can have a struct to hold the properties of each one.

A struct is implemented, and its components are accessed like this:

robotArm leftArm; leftArm.maxPos = 2000; leftArm.minPos = 150; leftArm.armSpeed = 100;
