Go语言指针数组

实例1：

package main

import "fmt"

const MAX int = 3

func main() {
    
    

   a := []int{
    
    10,100,200}
   var i int

   for i = 0; i < MAX; i++ {
    
    
      fmt.Printf("a[%d] = %d\n", i, a[i] )
   }
}

实例2：

package main

import "fmt"

const MAX int = 3

func main() {
    
    
   a := []int{
    
    10,100,200}
   var i int
   var ptr [MAX]*int;

   for  i = 0; i < MAX; i++ {
    
    
      ptr[i] = &a[i] /* 整数地址赋值给指针数组 */
   }

   for  i = 0; i < MAX; i++ {
    
    
      fmt.Printf("a[%d] = %d\n", i,*ptr[i] )
   }
}
