Exceptional C++ Herb Sutter

1. Chapter 1. Uses and Abuses of vector

　　Remember the difference between size/resize and capacity/reserve

　　Be as const correct. In particular, use const_iterator when you are not modifying the contents of a container.

　　Prefer comparing iterators with != not <. Because < works only with random-access iterators whereas != works with other iterator types too.

　　Prefer using prefix -- and ++, instead of postfix

　　Avoid needless recalculations.

　　Prefer '\n' to endl. Because using endl forces the stream to flush its internal output buffers.

　　Prefer reusing the standard library's copy and for_each instead of your own loops.

Chapter 1. Accustoming Yourself to C++

1. Item1: View C++ as a federation of languages.

2. Item2: Prefer consts, enums, and inlines to #defines

　　String objects are generally preferable to their char* based progenitors

　　As long as you don't take their address, you can declare class-specific constants that are static and of integral type without providing a definition.

　　What is an "enum heck"?

　　For simple constants, prefer const objects or enums to defines

　　For function-like macros, prefer inline functions to #defines

3. Item3: Use const whenever possible.

　　If the word const appears to the left of the *, what's pointed to is constant; if the word const appears to the right to the *, the pointer itself is constant.

　　When should a function return const?

　　Bitwise constness is C++'s definition of constness.

　　Compilers enforce bitwise constness, but you should program using logical constness.

　　When const and non-const member functions have essentially identical implementations, code duplication can be avoided by having the non-const version call the const version.
