Problem getting function correct.

Projects Programming
1

i cannot seem to find out what is wrong when compiling the following. I'm trying to learn how to use functions. I don't want to return any values, only pass parameters in to be used in i/o. What am I missing?

void setup() {
Serial.begin(9600);
}

void loop();
funct(3,5,6);
delay (500000);
}
void funct(int a, int b,int c){
int d=a + b + c;
Serial.println(d);
}

you missed a {

that s why I prefer the { opening bracket on the next line see below

void setup() 
{
  Serial.begin(9600);
}

void loop()
{
  funct(3,5,6);
  delay(5000);
}

void funct(int a, int b,int c)
{
  int d=a + b + c;
  Serial.println(d);
}

Thanks a lot - sometimes the obvious evades detection.

Your delay statement will not produce the intended results, either. Literals are treated as ints, and 500000 is not a valid int value. Either append UL to the end of the literal, or use a more reasonable approach, like not delay()ing at all.
