How do I set struct fields via reflection in Go?

In Go, you can set struct fields using reflection by utilizing the `reflect` package. This package allows you to inspect the type of objects at runtime and modify them as necessary. Below is an example of how you can set struct fields via reflection.

package main import ( "fmt" "reflect" ) type Person struct { Name string Age int } func main() { // Create an instance of Person p := Person{Name: "Alice", Age: 30} fmt.Println("Before:", p) // Get value and type of the struct v := reflect.ValueOf(&p).Elem() // Set the fields using reflection v.FieldByName("Name").SetString("Bob") v.FieldByName("Age").SetInt(25) fmt.Println("After:", p) }
