How to create array of references?

Question

I have a class named timeOut dealing with timeout tasks.

I'm to write a sketch, common for Sonoff basic and Sonoff Dual, meaning that I may have 1 task for Basic and 2 tasks for Dual.

Declaring instances looks like:

timeOUT timeOut_SW0("SW0",TIMEOUT_SW0);
timeOUT timeOut_SW0("SW1",TIMEOUT_SW1);

for code simplicity I'd rather create an array of references and call it using a for loop:

timeOUT TO[]={timeOut_SW0,timeOut_SW1};

is it the right way to call it as a reference ?

Answer 1

You can't. The C++ language doesn't support arrays of references. You have the choice to either create an array of objects:

timeOUT TO[] = {timeOUT("SW0",TIMEOUT_SW0), timeOUT("SW1",TIMEOUT_SW1);}

or an array of pointers:

timeOUT *TO[] = { &timeOut_SW0, &timeOut_SW1 };
