How do structs work in Go when dealing with concurrency?

In Go, structs are used to group related data together. When dealing with concurrency, it's important to manage access to these structs to avoid race conditions.

What are race conditions and how can I prevent them?

Race conditions occur when multiple goroutines access shared data simultaneously, leading to unpredictable results. You can prevent them using synchronization techniques like mutexes or channels.

Can you give an example of using a mutex with a struct?

Sure! Here's a simple example:

package main

import (
    "fmt"
    "sync"
)

type Counter struct {
    mu sync.Mutex
    value int
}

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

func main() {
    c := Counter{}
    // Use goroutines to increment the counter safely
}

What are channels and how do they relate to structs?

Channels in Go are used for communication between goroutines. You can use channels to send and receive structs, allowing safe data sharing without explicit locks.
