Pointers in Golang

Pointers in Go programming language or Golang is a variable that is used to store the memory address of another variable. Pointers in Golang is also termed as the special variables. The variables are used to store some data at a particular memory address in the system. The memory address is always found in hexadecimal format(starting with 0x like 0xFFAAF etc.).What is the need for the pointers? To understand this need, first, we have to understand the concept of variables. Variables are the names given to a memory location where the actual data is stored. To access the stored data we need the address of that particular memory location. To remember all the memory addresses(Hexadecimal Format) manually is an overhead that's why we use variables to store data and variables can be accessed just by using their name. 
Golang also allows saving a hexadecimal number into a variable using the literal expression i.e. number starting from 0x is a hexadecimal number.Example: In the below program, we are storing the hexadecimal number into a variable. But you can see that the type of values is int and saved as the decimal or you can say the decimal value of type int is storing. But the main point to explain this example is that we are storing a hexadecimal value(consider it a memory address) but it is not a pointer as it is not pointing to any other memory location of another variable. It is just a user-defined variable. So this arises the need for pointers.
 

// Golang program to demonstrate the variables
// storing the hexadecimal values
package main

import "fmt"

func main() {

    // storing the hexadecimal
    // values in variables
    x := 0xFF
    y := 0x9C
    
    // Displaying the values
    fmt.Printf("Type of variable x is %T\n", x)
    fmt.Printf("Value of x in hexadecimal is %X\n", x)
    fmt.Printf("Value of x in decimal is %v\n", x)
    
    fmt.Printf("Type of variable y is %T\n", y)
    fmt.Printf("Value of y in hexadecimal is %X\n", y)
    fmt.Printf("Value of y in decimal is %v\n", y)    
    
}

Output:  

Type of variable x is int
Value of x in hexadecimal is FF
Value of x in decimal is 255
Type of variable y is int
Value of y in hexadecimal is 9C
Value of y in decimal is 156
