Go 语言打印数组中的负数程序

编写一个 Go 程序，使用 For 循环在数组中打印负数。在这里，我们使用 for 循环 (for i = 0; i < ngsize; i++) 来迭代用户输入的数组项。在循环中，if 条件 (if negArr[i] < 0) 检查数字是否小于零。如果为 True，则表示它是负数，将其打印出来。

package main

import "fmt"

func main() {
    var ngsize, i int

    fmt.Print("Enter the Negative Array Size = ")
    fmt.Scan(&ngsize)

    negArr := make([]int, ngsize)

    fmt.Print("Enter the Negative Array Items  = ")
    for i = 0; i < ngsize; i++ {
        fmt.Scan(&negArr[i])
    }

    fmt.Print("\nThe Negative Numbers in this negArr = ")
    for i = 0; i < ngsize; i++ {
        if negArr[i] < 0 {
            fmt.Print(negArr[i], " ")
        }
    }
    fmt.Println()
}

Enter the Negative Array Size = 5
Enter the Negative Array Items  = 22 -9 11 -8 -15

The Negative Numbers in this negArr = -9 -8 -15 

Go 语言使用 For Loop Range 打印数组中的负数程序

package main

import "fmt"

func main() {
    var ngsize, i int

    fmt.Print("Enter the Negative Array Size = ")
    fmt.Scan(&ngsize)

    negArr := make([]int, ngsize)

    fmt.Print("Enter the Negative Array Items  = ")
    for i = 0; i < ngsize; i++ {
        fmt.Scan(&negArr[i])
    }

    fmt.Print("\nThe Negative Numbers in this negArr = ")
    for _, ng := range negArr {
        if ng < 0 {
            fmt.Print(ng, " ")
        }
    }
    fmt.Println()
}

Enter the Negative Array Size = 7
Enter the Negative Array Items  = 0 22 -90 -11 3 -2 2

The Negative Numbers in this negArr = -90 -11 -2 

在这个 Golang 程序中，我们创建了一个函数 (printNegativeNum(negArr []int)) 来打印给定数组中的负数。

package main

import "fmt"

func printNegativeNum(negArr []int) {
    fmt.Print("\nThe Negative Numbers in this negArr = ")
    for _, ng := range negArr {
        if ng < 0 {
            fmt.Print(ng, " ")
        }
    }
}

func main() {
    var ngsize, i int

    fmt.Print("Enter the Negative Array Size = ")
    fmt.Scan(&ngsize)

    negArr := make([]int, ngsize)

    fmt.Print("Enter the Negative Array Items  = ")
    for i = 0; i < ngsize; i++ {
        fmt.Scan(&negArr[i])
    }
    printNegativeNum(negArr)

    fmt.Println()
}

Enter the Negative Array Size = 5
Enter the Negative Array Items  = 11 -99 -66 0 -33

The Negative Numbers in this negArr = -99 -66 -33
