Golang 利用unsafe.Pointer进行指针操作
func main() {
data := []int{1, 2, 3}
for i := 0; i < len(data); i++ {
ptr := unsafe.Pointer(uintptr(unsafe.Pointer(&data[0])) + uintptr(i)*unsafe.Sizeof(data[0]))
fmt.Printf("%d ", *...

Golang 方法中指针传值的陷阱
package main
import "fmt"
type Person struct {
Name string
}
func (p Person) test1() {
p.Name = "www.gopher.cc"
fmt.Println(p.Name)
}
func (p *Person) test2() {
p.Name = "www.gopher.cc"
