Controlling five LEDs with a button in a sequence with Arduino.

Using modulus operator we can turn on and off LEDs in sequence.

By using arrays we can shorten the code as seen below

i'd like to do this with 1 button and only 3 led's what would the code look like for that ?

In the second program change
int numberOfLED = 5;
int numberOfLED = 3;
and use first 3 LED.

For the array I get the following errors, what's going on?

Button_Press-_Next_LED:1: error: expected unqualified-id before numeric constant
1: //
Button_Press-_Next_LED:9: error: expected unqualified-i
