Go语言中如何处理并发数据结构操作的问题？

package main

import (
    "fmt"
    "sync"
)

type Counter struct {
    mu    sync.Mutex
    count int
}

func (c *Counter) Increment() {
    c.mu.Lock()
    c.count++
    c.mu.Unlock()
}

func (c *Counter) GetCount() int {
    c.mu.Lock()
    defer c.mu.Unlock()
    return c.count
}

func main() {
    counter := Counter{}

    var wg sync.WaitGroup
    wg.Add(100)

    for i := 0; i < 100; i++ {
        go func() {
            counter.Increment()
            wg.Done()
        }()
    }

    wg.Wait()
    fmt.Println(counter.GetCount())
}

package main

import (
    "fmt"
    "sync"
    "time"
)

type Data struct {
    mu    sync.RWMutex
    value int
}

func (d *Data) Read() int {
    d.mu.RLock()
    defer d.mu.RUnlock()
    return d.value
}

func (d *Data) Write(value int) {
    d.mu.Lock()
    defer d.mu.Unlock()
    d.value = value
}

func main() {
    data := Data{}

    go func() {
        for {
            fmt.Println(data.Read())
            time.Sleep(time.Second)
        }
    }()

    for i := 0; i < 10; i++ {
        go func(value int) {
            data.Write(value)
        }(i)
    }

    time.Sleep(time.Second * 10)
}
