How do I use structs and fmt in Go?

In Go, structs are used to create complex data types. You can define a struct using the 'type' keyword. For example:

type Person struct {
    Name string
    Age  int
}

To format output, you can use the 'fmt' package. For instance, to print a struct, you can use:

fmt.Printf("%+v", person)

Can you show me an example of defining and using a struct?

Sure! Here's a complete example:

package main

import (
    "fmt"
)

type Person struct {
    Name string
    Age  int
}

func main() {
    p := Person{Name: "Alice", Age: 30}
    fmt.Printf("%+v
", p)
}

What if I want to format the output differently?

You can use different formatting verbs in the 'fmt' package. For example:

• %s for strings
• %d for integers

Here's how you can format the output:

fmt.Printf("Name: %s, Age: %d
", p.Name, p.Age)
