Thread: how to advance pointer in a for loop?

Could you instead use an index variable (let's call it i as an example) that you use in each member, e.g., SensorData.Vbias[0][i], SensorData.SiPMCurrent[0][i], etc.? Without more information on exactly why you need to have a pointer to the same element in each member, this smells like an XY problem.

Edit: I like hamster_nz's answer. Consider reorganizing your structure to do what you want to do.
