syntax: "using" and " class LiquidCrystal_I2C : public LCD {}" what does it mean

-

hi every one.

i newbie of arduino.

i open 1 lcd sample in libraries, when compiler error message appear, following message open include file.h know:

in lcd.h line 527 have statement: "using print::write;"

in liquidcrystal_i2c.h line 38 have statement: "class liquidcrystal_i2c : public lcd {....};

i read c++ documents dont see: syntax: "using"  , standard class define : classs  class _name{};

i dont understand 2 above statements, mean ?

thanks.

post full error compiler... issue in code , not library
