在全局声明区域使用using编译指令,将使得该名称空间的名称全局可用。这种情况其实我们已经非常熟悉了,因为我们一直在用using namespace std。 我们也可以在函数当中使用using编译指令: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 intmain(){using namespaceA;}...

The compiler imports the entire standard library when you useimport std;orimport std.compat;and does it faster than bringing in a single header file. It's faster to bring in the entire standard library withimport std;(orimport std.compat) than to#include <vector>, for example. ...
