Actually the keyword const is not for the programmer who work with the normal
general purpose computer. By declaring a variable as const, the compailar shows
warning/error to the modification to the variable. At runtime you can modify the memory location
using any technique, or an external hacking program can change the value of the variable.
Suppose your program is compiled to run with a microcontroller with flash or EEPROM or such
memory. Now your variable with const qualifier will be stored in the FLASH of EEPROM memory,
which cann't be modified, and the technique is used to save the RAM space which is too small in
size for a micro controller. In this case too, a FLASH/EEPROM write can chage the value of the
const varriable.
