In your newhelloworld.cppfile, hover overvectororstringto see type information. After the declaration of themsgvariable, start typingmsg.as you would when calling a member function. You should immediately see a completion list that shows all the member functions, and a window that shows the typ...

typedef std::map<int,std::vector<int>>Map1;using Map2=std::map<int,std::vector<int>>; 显然,这张重新声明别名的方式在通用性上很差,所以为了解决通用性问题,就需要使用template。 幸运的是,using可以直接创建模板别名: 代码语言:javascript
using Map = std::map<std::string, std::vector<std::string>>; MyInt a =3; Map m; 从上述示例看出,无论是使用typedef还是using都创建一个类型别名,他们的使用方式是一样的。也就是说到目前为止,看起来 typedef 和用法是相同的,但存在即合理,对using的引入肯定有其他原因,这就引入了typedef和using在模...

The function vatan2 outputs a vector z whose elements are atan(x[i]/y[i]), where i=0,..,*n–1. The function vsincos takes the arguments (y,z,x,n), and outputs two vectors, y and z, whose elements are sin(x[i]) and cos(x[i]), respectively. In vcosisin(y,x,n) ...
