Conditional serial.print

Using Arduino Programming Questions
1

Hi,

I came across something similar to the following :

serial.println(toggle ? F("OK") : F("NOT OK"))

It prints OK or NOT OK depending toggle being true or false

So this is a conditional printing and it works but I could not find this documented.

Is this C++ / Arduino compliant? Or a shortcut which one is not supposed to use?

It makes use of the only ternary operator in C. It is perfectly acceptable code.

It is the equivalent of

if (toggle)  //toggle is true
  {
    Serial.println("OK");
  }
else    //toggle is false
  {
    Serial.println("NOT OK");
  }

It is perfectly valid to use and is not restricted to being used with Serial.print
