使用 fmt.Scanf 来简化代码实现
package main
import (
// "bufio"
"fmt"
"math/rand"
// "os"
// "strconv"
// "strings"
"time"
)
func main() {
maxNum := 100
rand.Seed(time.Now().UnixNano())
secretNumber := rand.Intn(maxNum)
// fmt.Println("The secret number is ", secretNumber)
fmt.Println("Please input your guess")
// reader := bufio.NewReader(os.Stdin)
for {
var guess int
_, err := fmt.Scanf("%d",&guess);
// input, err := reader.ReadString('\n')
// if err != nil {
// fmt.Println("An error occured while reading input. Please try again", err)
// continue
// }
// input = strings.TrimSuffix(input, "\n")
// guess, err := strconv.Atoi(input)
if err != nil {
fmt.Println("Invalid input. Please enter an integer value")
continue
}
fmt.Println("You guess is", guess)
if guess > secretNumber {
fmt.Println("Your guess is bigger than the secret number. Please try again")
} else if guess < secretNumber {
fmt.Println("Your guess is smaller than the secret number. Please try again")
} else {
fmt.Println("Correct, you Legend!")
break
}
}
}

使用sync.WaitGroup，修改main()
func main() {
if len(os.Args) != 2 {
fmt.Fprintf(os.Stderr, `usage: simpleDict WORD
example: simpleDict hello
`)
os.Exit(1)
}
word := os.Args[1]
var wg sync.WaitGroup
wg.Add(2)
go func() {
defer wg.Done()
query(word)
}()
go func() {
defer wg.Done()
query2(word)
}()
wg.Wait()
}
