Void Setup error

When I try typing in my code, I get an error. Here it is:

exit status 1
variable or field 'setup' declared void

Do you think it might help if we could see your code ?

Please follow the advice given in the link below when posting code . Use code tags when posting code here to make it easier to read and copy for examination

Sure, Here is my code:

const int buzzPin = 11;
const int trigPin = 9;
const int echoPin = 10;
long duration;
int distance;

void setup {
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
Serial.begin(9600);
pinMode(buzzPin, OUPUT);
}

void loop() {
// Setting up the Distance Sensor:
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = duration*0.034/2;
Serial.print("Distance: ");
Serial.println(distance);

//Buzzer sound making

do {
tone(buzzPin, distance, 1);
}
while(1);

}

Why do users choose to ignore the advice on posting code ?

The easier you make it to read and copy your code the more likely it is that you will get help

Please follow the advice given in the link I posted

This is my setup:

void setup {
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
Serial.begin(9600);
pinMode(buzzPin, OUPUT);
}

This is the error message:

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

You need parenthesis after setup in order to make it a function definition instead of a variable definition:
void setup() {
You're already using the correct syntax for loop()...

@gablos are you deliberately ignoring the advice to use code tags when posting code and error messages ?
