解决方法:使用RAII(Resource Acquisition Is Initialization)原则,确保资源在对象构造时获取,在对象析构时释放。智能指针也可以帮助处理这种情况。 通过以上方法,可以有效地使用new来初始化C++类,并避免常见的内存管理问题。 相关搜索: 重新初始化使用new分配的pod类 为什么'new‘在类初始化中失败 使用new初始化嵌套结构...

absl::StrJoinnow has aabsl::string_viewoverload.This allows for passing a collection of string-like objects without having to convert everything to the same type first. However, this may be a breaking change for users passing an explicit template argument toabsl::StrJoin. In this case, sim...
