Printing Struct Variables in Console

To print the variables of a struct in the console in Go, you can use the fmt.Println() or fmt.Printf() functions from the fmt package.

Using fmt.Println()

The fmt.Println() function is a simple way to print the struct variables to the console.

Example

package main

import "fmt"

type Person struct {
    Name    string
    Age     int
    Country string
}

func main() {
    person := Person{
        Name:    "John",
        Age:     30,
        Country: "USA",
    }

    fmt.Println("Person:", person)
}

Using fmt.Printf() with %+v

If you need more control over the output or want to display the field names along with their values, you can use fmt.Printf() with the %+v verb.

Example

package main

import "fmt"

type Person struct {
    Name    string
    Age     int
    Country string
}

func main() {
    person := Person{
        Name:    "John",
        Age:     30,
        Country: "USA",
    }

    fmt.Printf("Name: %s, Age: %d, Country: %s\n", person.Name, person.Age, person.Country)
}

Using spew.Dump()

If you want a more detailed and formatted output, you can use a third-party package like spew to print the struct variables.

Example

package main

import (
    "github.com/davecgh/go-spew/spew"
)

type Person struct {
    Name    string
    Age     int
    Country string
}

func main() {
    person := Person{
        Name:    "John",
        Age:     30,
        Country: "USA",
    }

    spew.Dump(person)
}
