I have executed a small program to monitor temperature using internal sensor of DS3231RTC and to display it using I2C 16x2 LCD. I may include the following two header files in any combinations of double quotes and angle brackets; the program always works.
LiquidCrystal_I2C.h
Wire.h
When I searched my PC, I found the these header files under the directories as indicated.
LiquidCrystal_I2C.h : Could not trace the directory!?
Wire.h : c:\Program Files\Arduino\hardware\arduino\avr\libraries\Wire\src\Wire.h
My question: Is it really important for a programmer to care about the use of double quotes or angle brackets while including the header files? Traditionally, we are accustomed in the use of angle brackets.
