Comparison of pointers in Golang

Problem Solution:

In this program, we will perform the comparison on pointers based on addresses contained in pointer variables.

Program/Source Code:

The source code to demonstrate the comparison of pointers is given below. The given program is compiled and executed successfully.

Golang code to demonstrate the example of comparison of pointers

// Golang program to demonstrate
// the comparison of pointers

package main

import "fmt"

func main() {
	var val1 int = 10
	var val2 int = 20

	var ptr1 *int
	var ptr2 *int
	var ptr3 *int

	ptr1 = &val1
	ptr2 = &val2
	ptr3 = &val1

	if ptr1 == ptr2 {
		fmt.Println("ABC")
	} else {
		fmt.Println("XYZ")
	}

	if ptr1 == ptr3 {
		fmt.Println("ABC")
	} else {
		fmt.Println("XYZ")
	}
}

Output:

XYZ
ABC

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we created two integer variables and three-pointers. After that, we compared pointers and print appropriate messages based on comparison on the console screen.
