编译期展开和index_seq,在编译期将字符串加密。这个应该是目前C/C++程序员都使用过的方法。 cout << OBFUSCATED("Britney Spears") << endl; cout << (andrivet::ADVobfuscator::MetaString<3, 'k', std::make_index_sequence<sizeof("Britney Spears") - 1> >("Britney Spears").decrypt()) << endl...

In Visual Studio 2015, the compiler interprets this sequence as a user-defined literal, but since there is no matching user-defined literal _x defined, it gives an error. Output Copy error C3688: invalid literal suffix '_x'; literal operator or literal operator template 'operator ""_x'...
这句话的意思是说,在相邻两个序点(sequence point)之间,同一个数据对象的值最多可以通过表达式求值改变一次。 http://www.cnblogs.com/pmer/archive/2013/01/02/2842516.html 再比如,两个int类型数据相加,其前提条件是结果必须在int类型可以表示的范围之内,否则就成了一种未定义行为。
如果使用-xalias_level=strong 选项,则与 std 级别应用相同限制,但此外,编译器还假定类型 char * 的指针只用来访问类型为 char 的对象。此外,编译器还假定不存在内部指针。内部指针被定义为指向结构成员的指针。 B.2.73 - xannotate[=yes|no] (Solaris) 指示编译器创建以后可由诸如 binopt(1) 之类的二进制修...
