A long time ago, when I learned C language, when I put, data type, constant variables, statement control, functions, pointers, struct, custom data types, and some simple recursion, after the study, I thought I could pass the C language .. I saw a

1. Take C ++ as a new language learning (it has nothing to do with C! True ); 2. Read thinking in C ++ and do not read c ++ as a dead horse (C ++ programming ideology, very poor translation ); 3. Read the C ++ programming language (which has a photo

Clause 21: Use const whenever possible   The advantage of using const is that it allows you to specify a semantic constraint -- an object cannot be modified -- the compiler implements this constraint. With const, You can notify the compiler and
