How do get the array length?

MarkG:
You have an array...

int x[] = {}; // empty array

Exactly. It can hold ZERO elements.

you make a random number between 50 and 200

long y = random(50, 200);

OK. Useless, but, hey, it's your story.

you run a loop to then fill that array with a random number where the loop is 50 to 200 numbers

for(int c=0; c<=y-50; c++){

x[c] = random(1, 10);// stick a random number in it 1 to 10
}



Doing that is stupid, because there is space in the array for ZERO elements. You've, therefore, written over space that you don't own. That often has disastrous results.

When I run that in the Arduino to verify it, I get no errors.

Happy?

Yeah, but you won't be if you keep this crap up.
