Initialize variables using the 'for' command

[cdb0ewm]

I am working on a sketch that will turn on/off 10 LEDs. i.e., LED1, LED2, etc
Is there a way to use for 'for' command to define the individual LEDs like
for (int i = 0; i <= 10 i++) {
LED_(i);

I'm not sure of the format

LED1

Try this code:
Connect the LEDs to pins 2 to 11.

" LED_Sequence - Wokwi ESP32, STM32, Arduino Simulator

byte LED[] {2, 3, 4, 5, 6, 7, 8, 9, 10, 11};
//---------------------------------------------------------
void setup() {
  for (int i = 0; i < 10; i++)
  {
    pinMode(LED[i], OUTPUT);
  }
}
//---------------------------------------------------------
void loop() {
  for (int i = 0; i < 10; i++)
  {
    digitalWrite(LED[i], HIGH);
    delay(500);
  }
  for (int i = 0; i < 10; i++)
  {
    digitalWrite(LED[i], LOW);
    delay(500);
  }

  for (int i = 0; i < 10; i++)
  {
    digitalWrite(LED[i], HIGH);
    delay(500);
    digitalWrite(LED[i], LOW);
  }
}

See some tricks in these examples:

Flashing multiple LEDs at the same time

Introduction A common question is to ask how to flash 2 (or more) LEDs at the same time. Typically the person asking will be using delay and will be experiencing the main problem with delay: it blocks and stops anything else from happening. This tutorial contains several different approaches to the problem of flashing 2 or more LEDs at the same time with independent timing for each LED. The basic principles for each can all be adapted for other situations requiring multiple timers working inde…

What is 'LED_(i)' supposed to do? Is it a function? Is it a new syntax for defining a variable that you just made up?

Any variable defined in a 'for' loop will cease to exist upon exit from that loop.

Thank you both.. looks like I need to read up on byte
