#define number 108
In this case every instance of "number" will be replaced by the actual number 108 in your code, and this means the final compiled program will have the number 108 (in binary).
On the other hand, when you use const and the application runs, memory is allocated for the constant and the value gets replaced when the applicaton is ran:
const int number = 108;
