go Length of the array in Go
To find the length of an array in Go, you can use the built-in len()
function. Here is an example of how to use it:
package main
import "fmt"
func main() {
arr := [5]int{1, 2, 3, 4, 5}
length := len(arr)
fmt.Println("Length of the array:", length)
}
In this example, we first declare an array arr
with 5 elements of type int
. The values of the elements are {1, 2, 3, 4, 5}
.
Next, we use the len()
function to determine the length of the array. The result is assigned to the variable length
.
Finally, we print the value of length
using fmt.Println()
.
When you run this program, it will output:
Length of the array: 5
The len()
function returns the number of elements in the array. In this case, the array arr
has 5 elements, so the length is 5.
