import (
    "encoding/json"
    "fmt"
)

type User struct {
    ID        int    `json:"id"`
    Name      string `json:"name"`
    Email     string `json:"email"`
    IsActive  bool   `json:"is_active"`
}

func main() {
    user := User{
        ID:       1,
        Name:     "Alice",
        Email:    "alice@example.com",
        IsActive: true,
    }

    // Marshal to JSON
    data, err := json.Marshal(user)
    if err != nil {
        panic(err)
    }

    fmt.Println(string(data))
    // {"id":1,"name":"Alice","email":"alice@example.com","is_active":true}
}
