Golang program to get the type of specified variable

Here, we are going to learn how to get the type of specified variable in Golang (Go Language)?
Submitted by Nidhi, on March 24, 2021

Problem Solution:

In this program, we will create some variables of different types and get the type of variables using reflect.TypeOf() function and print the result on the console screen.

Program/Source Code:

The source code to get the type of specified variable is given below. The given program is compiled and executed successfully.

// Golang program to get the 
// type of specified variable

package main

import (
	"fmt"
	"reflect"
)

func main() {
	var num1 int = 10
	var num2 byte = 20
	var str string = "Hello"

	fmt.Println("Type of num1 is: ", reflect.TypeOf(num1))
	fmt.Println("Type of num2 is: ", reflect.TypeOf(num2))
	fmt.Println("Type of str is : ", reflect.TypeOf(str))
}

Output:

Type of num1 is:  int
Type of num2 is:  uint8
Type of str is :  string

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 and reflect packages to use time and reflect related functions.

In the main() function, we created three variable num1, num2, str that are initialized with 10, 20, "hello" respectively. Then we used reflect.TypeOf() function to get the type of specified variables and print them on the console screen.
