What is a good way to check if a array had expanded?

Hi All,

I have a expanding array that add in the current temperature value everytime my temperature sensor detect the current temperature to be 10°C and below. I would like to ask what is a good way to check if my array had expanded, example from 33 to 34 element?

Thank You!

You can use the size function.

Be aware, though, that organically "growing" an array like that, especially if it is large, will lead to poor memory usage, and slow execution time.

See, for example, this documentation on preallocation.
