On the Go Lang array

This is a creation in Article, where the information may have evolved or changed. One, array:
1: Arrays are value types, assignments, and delegates replicate the entire array instead of pointers
2: Array length must be constant for example, var a [3]int


Ii. Initialization of arrays
var a [3]int//DECLARE array variable
var a [3]int = [3]int{1,2,3}//initialized array, and is fixed length
A: = [3]int{1,2,3}//and above are equal
A:=[...] int{1,2,3,4,5,6}//Determine the length of an array by initializing the value


Three, array loop for range

For loop:


var Xun [5]int = [5]int{1, 2, 3, 4, 5}
For xn: = 0; xn < Len (Xun); xn++ {
Fmt. Println (Xun[xn])
}

Range: Loop


For k, V: = Range Xun {
Fmt. Println (k)//Get key value
Fmt. Println (v)//value
}


Four: Array functions


Both the built-in function Len and the CAP return the array ⻓ length (number of elements).
