how do I return the array value as an integer from the text file?

Tjess

can somebody tell me what I am doing wrong? I can't see it anymore. I think it is simple, but after staring at it for several hours I give up...

int geefCijfer (int[] cijfer1) {
  String [] cijfers =loadStrings("cijfers_klein.txt");
  int [] cijfer = new int [cijfers.length];
  for (int i = 0; i< cijfers.length; i++) {
    cijfer[i] = int(cijfers[i]);
    println(cijfer);
  } 
  return cijfer;
}

At the beginning

you want int[] since you return an array

kfrajer

This next should work (untested):

int[] geefCijfer (int[] cijfer1) {
  return int(loadStrings("cijfers_klein.txt"));
}

I doubt it ;-)

To get real help please post an entire code that’s runnable or a short version of it to demonstrate the problem

And the first 10 lines of your file also formatted as code

Chrisir

void setup() {
  int[]  c1 =  geefCijfer();
  println("-------------");
  printArray(c1);
}

int[] geefCijfer () {
  String [] cijfers = {"1", "9", "8"}; // loadStrings("cijfers_klein.txt");
  int [] cijfer = new int [cijfers.length];
  for (int i = 0; i< cijfers.length; i++) {
    cijfer[i] = int(cijfers[i]);
  }
  printArray(cijfer);
  return cijfer;
}

Chrisir

but kfrajer is right !!!

void setup() {
  int[]  c1 =  geefCijfer();
  println("-------------");
  printArray(c1);
}

int[] geefCijfer () {
  String [] cijfers = {"1", "9", "8"}; // loadStrings("cijfers_klein.txt");
  printArray(cijfers);
  return int(cijfers);
}
