有一个例外是using namspace std::literals;。如果需要在头文件中使用字符串字面值而且满足这样的条件:用户被要求为他们自己的UDL运算符“”_x命名而且他们不会和标准库相冲突,使用using namespace std::literals是就可以认为是必要的。 Enforcement(实施建议) Flag using namespace at global scope in a header fi...

说明using namespace qt::stringliterals; 在代码中的具体应用 当你在代码中包含 using namespace Qt::StringLiterals; 时,你可以直接使用这些字面量运算符来创建Qt类型的实例,而不需要显式地指定命名空间。 例如: cpp #include <QString> using namespace Qt::StringLiterals; int main() { auto ch ...

The using-directiveusing namespace std;tells the compiler that all of the names in thestdnamespace should be accessible without qualification in the current scope (in this case, of functionmain()). When we then use unqualified identifiercout, it will resolve tostd::cout. ...
The C++11 standard has introduced a new type of namespace called inline namespaces that are basically a mechanism that makes declarations from a nested namespace look and act like they were part of the surrounding namespace. Inline namespaces are declared using the inline keyword in the name...
