rg - 容器兼容范围,即其元素可以转换为 T 的input_range 类型要求 - T 必须从 *ranges::begin(rg) 向vector 可就位构造 (EmplaceConstructible) 。而且,T 必须向 vector 可移动插入 (MoveInsertable) 且T 必须满足可移动构造 (MoveConstructible) ,可移动赋值 (MoveAssignable) ,和可交换 (Swappable) 。否...

- `std::vector`在一定程度上可以通过`at()`函数进行安全的边界检查访问。如果使用`at()`函数访问超出范围的索引，会抛出`std::out_of_range`异常，帮助程序员更容易地发现错误。- 例如：#include <iostream> #include <vector> int main() { std::vector<int> myVector = {1, 2, 3};try { std::c...
