I would like to make this code using the Arduino Uno. I am using three on/off switches and based on the truth table would like to turn on one of 8 LEDs. When I use digitalWrite(), I get an error code saying that there are too few arguments.

Here is the code

int x = A3;    // select the input pin for the switch
int y = A4;
int z = A5;




int ledPin1 = 2;      // select the pin for the LED
int ledPin2 = 3;
int ledPin3 = 4;
int ledPin4 = 7;
int ledPin5 = 8;
int ledPin6 = 9;
int ledPin7 = 12;
int ledPin8 = 13;

void setup() {
  // declare the ledPin as an OUTPUT:
  pinMode(ledPin1, OUTPUT);
  pinMode(ledPin2, OUTPUT);
  pinMode(ledPin3, OUTPUT);
  pinMode(ledPin4, OUTPUT);
  pinMode(ledPin5, OUTPUT);
  pinMode(ledPin6, OUTPUT);
  pinMode(ledPin7, OUTPUT);
  pinMode(ledPin8, OUTPUT);
  
  pinMode(x, INPUT);
  pinMode(y, INPUT);
  pinMode(z, INPUT);
  
}

void loop() {
  
  if ( (x = LOW) && (y = LOW) && (z = LOW))              //condition 1
