Problem declaring and using an array

Projects Programming
1

I haven't used the IDE for a while, and I can't see what's wrong with this:

float sensors[3];
sensors[0]=123.0;


void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

Error message:

this is outside a function. could put in in setup() or do this instead

float sensors[3] = { 123.0 };

D'oh! Thanks!
