void writereg() {
  digitalWrite(latchPin, LOW);
  for (int i = 7; i >= 0; i--) {
    digitalWrite(clockPin, LOW);
    Serial.print("wswitch&&&&&&");
    Serial.print(i);
    Serial.print("----------------------");
    digitalWrite(dataPin, switches[i].stat);
    Serial.println(switches[i].stat);
    digitalWrite(clockPin, HIGH);
  }
  digitalWrite(latchPin, HIGH);
  touched = false;
}

I don't understand what's wrong with what I'm doing here, but this for loop runs into an almost infinite loop and prints crazily. I'm a newbie to electronics and Arduino and I don't understand what's wrong here. Please help.
