为什么我收到非数字类型* int错误？

Question

I am getting non-numeric type *int error in the example below, why ?

func main() {
    count := 0
    for {
        counting(&count)
    }
}

func counting(count *int) {
    fmt.Println(count)
    count++
}

You need to derefence the pointer:

package main

import (
    "fmt"
)

func main() {
    count := 0
    for i:=0; i<10; i++ {
        counting(&count)
    }
}

func counting(count *int) {
    fmt.Println(*count)
    *count++
}
