How do I use a map with struct keys in Go?

In Go, you can use a map with struct keys to associate values with specific instances of a struct. This enables powerful data handling and organization capabilities in your applications.
Go, structs, maps, key-value pairs, programming
package main import ( "fmt" ) // Define a struct type Person struct { Name string Age int } func main() { // Create a map with Person struct as keys people := make(map[Person]string) // Create some Person instances john := Person{Name: "John", Age: 30} jane := Person{Name: "Jane", Age: 25} // Add entries to the map people[john] = "Engineer" people[jane] = "Designer" // Access and print the values for person, occupation := range people { fmt.Printf("%s is a %s\n", person.Name, occupation) } }
