package main
import (
"fmt"
"time"
)
func main() {
names := []string{"Eric", "Harry", "Robert", "Jim", "Mark"}
for _, name := range names {
go func() {
fmt.Printf("Hello, %s!\n", name)
}()
}
time.Sleep(time.Millisecond)
}
结果:
package main
import (
"fmt"
"time"
)
func main() {
names := []string{"Eric", "Harry", "Robert", "Jim", "Mark"}
for _, name := range names {
go func() {
fmt.Printf("Hello, %s!\n", name)
}()
}
time.Sleep(time.Millisecond)
}
package main
import (
"fmt"
"time"
)
func main() {
names := []string{"Eric", "Harry", "Robert", "Jim", "Mark"}
for _, name := range names {
go func(who string) {
fmt.Printf("Hello, %s!\n", who)
}(name)
}
time.Sleep(time.Millisecond)
}
结果:
package main
import (
"fmt"
"time"
)
func main() {
names := []string{"Eric", "Harry", "Robert", "Jim", "Mark"}
for _, name := range names {
go func(who string) {
fmt.Printf("Hello, %s!\n", who)
}(name)
}
time.Sleep(time.Millisecond)
}
为什么第二段就能正常的迭代了呢?
