append 函数的参数长度可变,因此可以追加多个值到 slice 中,还可以用 ... 传入 slice,直接追加一个切片。 1 2 slice = append(slice, elem1, elem2) slice = append(slice, anotherSlice...) append函数返回值是一个新的slice,Go编译器不允许调用了 append 函数后不使用
函数append()是golang用于操作切片的内置函数,先看看函数定义:// The append built-in function appends elements to the end of a slice. If // it has sufficient capacity, the destination is resliced to …
// slice = append(slice, anotherSlice...) // As a special case, it is legal to append a string to a byte slice, like this: // slice = append([]byte("hello "), "world"...) func append(slice []Type, elems ...Type) []Type append 会追加一个或多个数据至 slice 中,这些数据...
It is therefore necessary to store the // result of append, often in the variable holding the slice itself: // slice = append(slice, elem1, elem2) // slice = append(slice, anotherSlice...) // As a special case, it is legal to append a string to a byte slice, like this: //...
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, any change in one affects...

切片(Slice)是Golang中非常重要的数据结构,它可以动态地调整大小,并且常用于处理集合的情况。在本文中,我们将系统地介绍切片的概念、语法和修改方式,并逐一讲解len()、cap()、append()和copy()函数的用法。通过学习本文,读者将更加熟悉切片的操作,提高对Golang的掌握程度。
