如何将一个字符串数组复制到另一个字符串数组？

Question

我有一个字符串元素数组，我希望将这些值复制到一个新的数组中。我可以怎么做？

Answer 1

You can declare a new array of the same type and copy over the values by assigning it.

// Declare a string array of five elements.
var array1 [5]string

// Declare a second string array of five elements.
// Initialise the array with values.
array2 := [5]string{"A", "B", "C", "D", "E"}

// Copy the values from array2 into array1.
array1 = array2

---

Keep in mind that you cannot assign over an array of different size:

// Declare a string array of four elements.
var array1 [4]string

// Declare a second string array of five elements.
// Initialize the array with colors.
array2 := [5]string{"A", "B", "C", "D", "E"}

// Copy the values from array2 into array1.
array1 = array2

Compiler Error:
cannot use array2 (type [5]string) as type [4]string in assignment
