Expected Unqualified-Id Before ')' Token

Using Arduino Programming Questions
1

I just wrote an Arduino program, but I keep receiving the following error:
"Expected Unqualified-Id Before ')' Token"
I've tried removing chunks of code and recompiling, but regardless of what code I remove, I still get this error, with one of the first 4 lines highlighted with the error. Here's my code:

const int ledCharge1 = 8;
const int ledCharge2 = 9;
const int ledCharge3 = 10;
const int ledRun = 13;
const int modeInLocal = 2;
const int modeInAuto = 3;
const int inStart = 5;
const int inStop = 6;
const int localState = 0;
int i = 0;

void setup() {
  pinMode(ledCharge1, OUTPUT);
  pinMode(ledCharge2, OUTPUT);
  pinMode(ledCharge3, OUTPUT);
  pinMode(ledRun, OUTPUT);
  pinMode(modeInLocal, INPUT);
  pinMode(modeInAuto, INPUT);
  pinMode(inStart, INPUT);
  pinMode(inStop, INPUT);
}

void loop() {
  int localState = digitalRead(modeInLocal);
  if (localState == LOW) {
    local;
  }
  
  int autoState = digitalRead(modeInAuto);
  if (autoState == LOW) {
    auto;
  }
  
  if (localState == HIGH && autoState == HIGH) {
    digitalWrite(ledCharge1, LOW);
    digitalWrite(ledCharge2, LOW);
    digitalWrite(ledCharge3, LOW);
    digitalWrite(ledRun, LOW);
  }
}

void auto() {
  for (int i = 0; i < 3; i++) {
    digitalWrite(ledCharge1, HIGH);
    delay(750);
    digitalWrite(ledCharge1, LOW);
    delay(750);
  }
  
  digitalWrite(ledCharge1, HIGH);
  
  for (int i = 0; i < 3; i++) {
    digitalWrite(ledCharge2, HIGH);
    delay(750);
    digitalWrite(ledCharge2, LOW);
    delay(750);
  }
  
  digitalWrite(ledCharge2, HIGH);
  
  for (int i = 0; i < 3; i++) {
    digitalWrite(ledCharge3, HIGH);
    delay(750);
    digitalWrite(ledCharge3, LOW);
    delay(750);
  }
  
  digitalWrite(ledCharge3, HIGH);
  digitalWrite(ledRun, HIGH);
  
  for (int i = 0; i < 5; i++) {
    digitalWrite(ledCharge3, HIGH);
    delay(750);
    digitalWrite(ledCharge3, LOW);
    delay(750);
  }
  
  for (int i = 0; i < 5; i++) {
    digitalWrite(ledCharge2, HIGH);
    delay(750);
    digitalWrite(ledCharge2, LOW);
    delay(750);
  }
  
  for (int i = 0; i < 3; i++) {
    digitalWrite(ledCharge1, HIGH);
    delay(750);
    digitalWrite(ledCharge1, LOW);
    delay(750);
  }
  
  digitalWrite(ledRun, LOW);
}

Like I said, it's always one of the first 4 lines, even when I remove the first half of the program (or any chunk of it, for that matter) and try again. What's happening?

Oh, also, there's one function I haven't put in yet. (You may notice a reference to it in the "loop" function.) I just want to get this sorted out before I finish it up and have more possible errors to worry about.

"auto" is a keyword in C.

And you have an undefined reference to "local", and you are not calling
either as a function, you have to provide an empty arglist.

You need to call your functions with () on the end of them, not just local; or auto;

The problem is what the other 2 users said. So, try the following code:

const int ledCharge1 = 8;
const int ledCharge2 = 9;
const int ledCharge3 = 10;
const int ledRun = 13;
const int modeInLocal = 2;
const int modeInAuto = 3;
const int inStart = 5;
const int inStop = 6;
const int localState = 0;
int i = 0;

void setup() {
  pinMode(ledCharge1, OUTPUT);
  pinMode(ledCharge2, OUTPUT);
  pinMode(ledCharge3, OUTPUT);
  pinMode(ledRun, OUTPUT);
  pinMode(modeInLocal, INPUT);
  pinMode(modeInAuto, INPUT);
  pinMode(inStart, INPUT);
  pinMode(inStop, INPUT);
}

void loop() {
  int localState = digitalRead(modeInLocal);
  if (localState == LOW) {
    fun_local();
  }
  
  int autoState = digitalRead(modeInAuto);
  if (autoState == LOW) {
    fun_auto();
  }
  
  if (localState == HIGH && autoState == HIGH) {
    digitalWrite(ledCharge1, LOW);
    digitalWrite(ledCharge2, LOW);
    digitalWrite(ledCharge3, LOW);
    digitalWrite(ledRun, LOW);
  }
}

void fun_auto() {
  for (int i = 0; i < 3; i++) {
    digitalWrite(ledCharge1, HIGH);
    delay(750);
    digitalWrite(ledCharge1, LOW);
    delay(750);
  }
  
  digitalWrite(ledCharge1, HIGH);
  
  for (int i = 0; i < 3; i++) {
    digitalWrite(ledCharge2, HIGH);
    delay(750);
    digitalWrite(ledCharge2, LOW);
    delay(750);
  }
  
  digitalWrite(ledCharge2, HIGH);
  
  for (int i = 0; i < 3; i++) {
    digitalWrite(ledCharge3, HIGH);
    delay(750);
    digitalWrite(ledCharge3, LOW);
    delay(750);
  }
  
  digitalWrite(ledCharge3, HIGH);
  digitalWrite(ledRun, HIGH);
  
  for (int i = 0; i < 5; i++) {
    digitalWrite(ledCharge3, HIGH);
    delay(750);
    digitalWrite(ledCharge3, LOW);
    delay(750);
  }
  
  for (int i = 0; i < 5; i++) {
    digitalWrite(ledCharge2, HIGH);
    delay(750);
    digitalWrite(ledCharge2, LOW);
    delay(750);
  }
  
  for (int i = 0; i < 3; i++) {
    digitalWrite(ledCharge1, HIGH);
    delay(750);
    digitalWrite(ledCharge1, LOW);
    delay(750);
  }
  
  digitalWrite(ledRun, LOW);
}

void fun_local() {
// Do nothing!
}
