Q.8
Major reasons for writing programs in C for AVR programing are
  • It is easier and less time consuming to write in C than in Assembly.
  • C is easier to modify and update.
  • You can use code available in function libraries.
  • C code is portable to other microcontrollers with little or no modification.
  • All of above
