The Arduino UNO keeps rebooting and thus running void setup(). This can happen after the ATmega 328p has been flashed. Turn the Arduino UNO off and on to resolve the issue
It is normally not the watchdog timer reset: wdt_reset();

In stead of using the Arduino serial monitor one can use a terminal in Linux:

screen /dev/ttyUSB0 57600

seems to block the serial interface. When this happens it can be solved

• close the screen command
• close the terminal window in which screen was running
• close the Arduino IDE
• close the text editor if you are using it instead of the Arduino IDE
• disconnect the USB cable
• reconnect the USB cable
• start the Arduino IDE.

if (Serial) { Serial.printnl(The link is up); }
while (!Serial) {
  // Wait for the link to become up
  delay(100);
}

This does not work

  int j=7 k-8;
  Serial.println("j: " + j + "\tk: " + k);

use

  int j=7 k-8;
  String js = "j: ";
  String ks = "\tk: ";
  Serial.println(js + j + ks + k);

instead
