在Go语言中将Struct数组元素作为参数传递给函数

package main

import "fmt"

type Person struct {
    Name string
    Age  int
}

func updateAge(p Person) {
    p.Age = 30
}

func updateAgeByPointer(p *Person) {
    p.Age = 30
}

func main() {
    people := []Person{
        {"Alice", 25},
        {"Bob", 30},
        {"Charlie", 35},
    }

    fmt.Println("Before updateAge:", people)
    for i := range people {
        updateAge(people[i])
    }
    fmt.Println("After updateAge:", people)

    fmt.Println("Before updateAgeByPointer:", people)
    for i := range people {
        updateAgeByPointer(&people[i])
    }
    fmt.Println("After updateAgeByPointer:", people)
}

Before updateAge: [{Alice 25} {Bob 30} {Charlie 35}]
After updateAge: [{Alice 25} {Bob 30} {Charlie 35}]
Before updateAgeByPointer: [{Alice 25} {Bob 30} {Charlie 35}]
After updateAgeByPointer: [{Alice 30} {Bob 30} {Charlie 30}]
