Error: expected initializer before 'int'

Using Arduino Project Guidance
1

The project i am currently working on (automated humidifier) needs to be programmed. i found someone who had already completed this project online and though i would use their example to get started because i really know nothing about programming. the problem is this code has an error in the first line. can anyone help/ tell me what an expected initializer is?

void loop()

int 1 enum Mode {
   ModeNormal = 0,
   ModeSetting
 };
 Mode systemMode = ModeNormal;

 void updateEncoder9() {
  long newPosition = encoder.read();
  if (newPosition != target){
    if (systemMode == ModeSetting)
      target = newPostion;
  }
 }

 void updateData() {
  readSensors();

  if (correct && humidity <= (target - hysteresis))
    correct = false;
  else if (!correct && humidity >= (target + hysteresis))
    correct = true;

  refreshLEDs(correct);
  updateRelay(!correct);
  }

Fix this line

int 1 enum Mode {

And do again.

When you get a 1000 errors it's not normally as bad as it seems, start at the first one and after 2-3 they have usually all gone.

the problem is that i dont know what is wrong with this line, im not good with programming, im just using this as an example.

Graynomad:

Why is there "int 1" before the "enum Mode {"?

Either delete "int 1" or you missed a variable name, equal sign, and a semicolon. It should either be:

enum Mode {...}

or

int variable = 1;
enum Mode {

Take a look at enumerated types here.
