chatGPT generates code --go starts multithreading

Question: Write a startup function createTask(names[]string) in golang. Function: Start n threads, the number of threads is the length of names, and the thread name is the value of names. It is necessary to wait for all threads to start before executing the function and returning

Code: Here is a function written in Golang createTaskthat starts namesas many goroutines as there are names in the slice and waits for them all to finish before returning:

package main

import (
	"fmt"
	"sync"
)

func createTask(names []string) {
	var wg sync.WaitGroup

	for _, name := range names {
		wg.Add(1)

		go func(n string) {
			defer wg.Done()
			fmt.Printf("线程 %s 启动\n", n)
			// 在这里可以执行线程需要做的工作
		}(name)
	}

	wg.Wait() // 等待所有线程完成
	fmt.Println("所有线程已启动完成，函数返回")
}

func main() {
	names := []string{"Thread1", "Thread2", "Thread3"}

	createTask(names)
}
