Go, often known as Golang, is an open-source, compiled, and statically typed computer language created by Google. It is intended to be simple, quick, readable, and efficient.

Today, we will discuss finding the length of the pointer in Go. But before, let's learn about what a pointer in Go is.


Pointers are the Go programming language variables used to hold another variable's memory address. Pointers are also known as special variables in Golang. The variables store data in the system at a specific memory address. Memory addresses are always in hexadecimal format eg.0xA012

Finding Length of the Pointer

The length of a pointer may be determined using the len() method in pointers. This built-in function returns the total number of items in the supplied pointer to an array, even if the specified pointer is null. This function is classified as builtin.


func len(p Type) int
Here, p is the pointer.


Let's go through an example to have a better understanding.

// How to find the length of the pointer to an array using the Go language
package main
import (

func main() {
    var pointer1 [5]*int
    var pointer2 [4]*string
    var pointer3 [3]*float64
    // Finding the length of Pointer Array
    fmt.Println("Length of Pointer 1: ", len(pointer1))
    fmt.Println("Length of Pointer 2: ", len(pointer2))
    fmt.Println("Length of Pointer 3: ", len(pointer3))



​​Length of Pointer 1:  5
Length of Pointer 2:  4
Length of Pointer 3:  3

Frequently Asked Questions

What is Go?
