Array

An array is a collection of variables of the same type and name.

Array element: each variable in an array.

Array index: also called as key, the numbers on each element.

Note: the array index or array key starts from zero.

There are several kinds of way to define an array:

(1)

var array_name[ length] type // define an array

array_name[key] = value // assign value to the element

Example 6.1

package main

func main(){

var arr [3]int // define an array with three elements

arr[0]=100 // assign a value to the array element

arr[1]=101

arr[2]=102

print(arr[0], " ", arr[1], " ", arr[2])

}
