before_append After appending: Here you can see the value of the underlying array of the slice gets changed after the append: after_append This can also be verified by checking the memory address of the underlying array. Since both of the slice point to a same underlying array memory address...

函数说明:内建函数append追加一个或多个elems到一个slice依赖的array的末尾,如果这个slice有足够的capacity,则reslice以容纳新增元素;如果capacity空间不够,则重新分配内存保存新的slice依赖的array,函数返回更新后的slice.(slice是引用,array保存真正的数据,slice切片理解:https://blog.haohtml.com/arch...) 注意:app...

Golang Slice and Append Function A slice is a portion or segment of an array. Or it is a view or partial view of an underlying array to which it points. You can access the elements of a slice using the slice name and index number just as you do in an array. You cannot change the...
The length is the number of elements referred to by the slice. The capacity is the number of elements in the underlying array (beginning at the element referred to by the slice pointer). The distinction between length and capacity will be made clear as we walk through the next few examples...
