error: size of array 'momentumOfparticles' has non-integral type 'float [i]'

[J-M-L]

dougp:
That makes sense. What is the cause then of "error: size of array 'momentumOfparticles' has non-integral type 'float'" ?

it's telling you it's a pointer to an array of float which it does not like (but not a float)
