SUMMARY
The '->' operator in C++ is used to access members of a class or structure through a pointer. In the example provided, "pTerm = pid->pGain * error;", 'pid' is a pointer to a class or structure, and 'pGain' is a member of that class or structure. The expression 'pid->pGain' is functionally equivalent to dereferencing the pointer with '(*pid).pGain', but the '->' operator offers a more concise and readable syntax.
