go语言笔记——append底层实现和Cpp vector无异,只是有返回值,double后返回了新的vector地址而已 切片的复制与追加 如果想增加切片的容量,我们必须创建一个新的更大的切片并把原分片的内容都拷贝过来。下面的代码描述了从拷贝切片的 copy 函数和向切片追加新元素的 append 函数。 示例7.12copy_ap

inplace_vector provides the basic exception safety guarantee, i.e., all elements of the container before the call are preserved, and all already inserted elements (before the exception, if any) are also preserved. NotesThis section is incompleteReason: Explain the purpose of this API. Example...
