列表初始化返回值 vector<string>pro(){ return {"one","two"}; } 1. 2. 3. 如果返回内置类型则{}中最多包含一个值 返回数组指针 数组不能拷贝,所以函数不能返回数组 使用类型别名简化返回数组的指针和引用 //下面两行代码是等价的 typedef int arr[10]; using arr = int[10]; //返

最后试着用上面的配置器(allocator、constructor和uninitialized)写一个简单的vector容器: /*vector.h*/#include<memory>#include"my_alloc.h"#include"my_construct.h"template<classT,classAlloc=alloc>classvector {public: typedef T value_type; typedef T*pointer; ...
通过fs.openSync获得的fd,传递到C侧调close后,ArkTS侧fs.closeSync是不是不用调了 如何校验文件一致性 文件路径fd和internal的区别是什么 使用request.uploadFile上传文件后,没有回调可以获取到服务器返回的message信息,不能明确知道文件是否上传成功 fs接口写文件,两次调用,第二次写入的内容比第一次写入的内容...

In the C++ STL, the vector size() function return size_t, which is unsigned int, not int. So imagine this, define an empty vector v, and v.size() shou
