只是为了让大家都知道编程方面的新知识，我想我只是想念一些小东西，但我不知道它是什么。编译代码时，出现此错误“格式%d期望匹配的int自变量[-Wformat=]”。我已经尝试了很多东西。我尝试将所有函数类型都设置为char，并将它们全部都设置为int。我收到类似的错误。
char *phoneInput(void)
{
char phone[11];
printf("Input the politicians phone number with no spaces: ");
fgets(phone, 10, stdin);
return 0;
}
char printPhone(char phone[11])
{
printf("- Phone Number: (%d%d%d)%d%d%d-%d%d%d%d", phone[0], phone[1], phone[2],
phone[3], phone[5], phone[6], phone[7], phone[8], phone[9]);
return 0;
}
答案 0 :(得分：1)
您的// Event struct
type Event struct {
Name string
Data interface{}
}
// Stream to publish events to
var stream = make(chan *Event, 100)
// Publish sends new event data to the stream by the event name
func Publish(name string, data interface{}) {
ev := &Event{name, data}
stream <- ev
}
// Handler provides the interface for all event handlers.
// The Work will be called with the event that it should process
type Handler interface {
Work(*Event)
}
type worker struct {
Handler
Listen chan *Event
Quit chan bool
}
// Stop shuts down the worker
func (w *worker) Stop() {
go func() {
w.Quit <- true
}()
}
// Queue of worker Listen channels
type workerQueue chan chan *Event
// registry of workers
var registry = make(map[string][]workerQueue)
// Register creates 20 workers, assigns them to a queue, and
// appends the resulting worker queue to an event on the handler registry
func Register(name string, handlers ...Handler) {
if _, ok := registry[name]; !ok {
registry[name] = make([]workerQueue, 0)
}
// Create workerQueues for each handler
for _, h := range handlers {
queue := make(workerQueue, numListeners)
// Create 20 workers
for i := 0; i < 20; i++ {
newWorker := worker{
Handler: h,
Listen: make(chan *Event),
Quit: make(chan bool),
}
go func() {
for {
select {
case ev := <-newWorker.Listen:
nl.Work(ev)
case <-newWorker.Quit:
return
}
}
}()
queue <- newWorker.Listen
}
registry[name] = append(registry[name], queue)
}
}
// Start begins listening for events on stream
func Start() {
go func() {
for {
select {
// listen for events
case ev := <-stream:
go func() {
// get registered queues for the event
queues, ok := registry[ev.Name]
if !ok {
return
}
// Get worker channel from queue and send the event
for _, queue := range queues {
worker := <-queue
worker <- ev
}
}()
}
}
}()
}
语句缺少一个参数。像这样将// Usage
Start()
type demoHandler struct {
db *sql.DB
}
type eventData struct {}
func (h *demoHandler) Work(ev *Event) {
// Do something
return
}
// Register handler
Register('some-event', &demoHandler{r})
Publish('some-event', &eventData{})
添加到您的printf。
phone[4]但是我不明白，为什么实际上所有两个函数都只返回printf，所以为什么所有函数的返回类型都是#include <iostream>
using namespace std;
char *phoneInput(void)
{
char phone[11];
printf("Input the politicians phone number with no spaces: ");
fgets(phone, 10, stdin);
return 0;
}
char printPhone(char phone[11])
{
printf("- Phone Number: (%d%d%d)%d%d%d-%d%d%d%d", phone[0], phone[1], phone[2],
phone[3], phone[4], phone[5], phone[6], phone[7], phone[8], phone[9]);
return 0;
}
或char*。 / p>
