这个简单的脚本怎么了? [英] What's wrong with this simple script?

问题描述

我学习了函数，为教科书写了一个简单的脚本，有两个错误.

I study functions, wrote a simple script for the textbook, and there were 2 errors.

package main
import "fmt"

func zero(x int) {
    x = 0
    return x
}
func main() {
    x := 5
    x = zero(x)
    fmt.Println(x)
}

要返回的参数太多(字符串返回x)

too many arguments to return (string return x)

太多"了吗?只有一个！

How is "too many"? It's only one!

零(x)用作值(字符串x =零(x))

zero(x) used as value (string x = zero(x))

我不明白他对我说的话.

I don't understand what he says to me.

推荐答案

int in func

int in func

package main
import "fmt"

func zero(x int) int {
    x = 0
    return x
}
func main() {
    x := 5
    x = zero(x)
    fmt.Println(x)
}
