I've been reading about the problems with using the string class. How do I know if I'm using the string class? Would any of these use the string class

  • Serial.println("Hello")
  • Wire.h library
  • Ethernet.h library
  • strcpy()
  • strcat()
  • sprintf()
  • dtostrf()

No, none of your examples use the String class.
