Hello cookiesss

Welcome to the world's best Arduino forum ever.

Consider:

enum LedNames {Red,Green};
constexpr uint8_t LedPins[] {9,10};  // [port pin] --  -->|--  -- [GND]
constexpr uint8_t ButtonPin {A0};    // [port pin] -- [button] -- [GND]

void setup() 
{
  for (auto LedPin:LedPins) pinMode(LedPin,OUTPUT);
  pinMode(ButtonPin,INPUT_PULLUP);
}
void loop() 
{
  digitalWrite(LedPins[Green],digitalRead(ButtonPin)?LOW:HIGH);
  digitalWrite(LedPins[Red],digitalRead(LedPins[Green])?LOW:HIGH);
}

Have a nice day and enjoy coding in C++.
