1. ► A constant function cannot have side-effects

2. ► C++ doesn’t allow type mismatches

3. ► Using const is a good design practice to avoid the possibility of side-effects

4. ► A const value can be made to change via static_cast

5. ► Templates allow optimizations because of:

6. ► ‘int *’ is same as ‘const int *’

7. ► ‘const int *’ is same as ‘int const *’

8. ► Templates are used for making a function or a class type agnostic

9. ► Templates are type-safe

10. ► Template compilation is slow because of:

11. ► Constants allow compiler optimizations

12. ► In ‘int * const’, interger value is a constant

13. ► Templates can be used to provide compile time constraints

14. ► Templates are mostly used for generic containers

15. ► dynamic_cast is used to find out the exact type of template class at run-time

16. ► Template types are checked at run-time
