Go 程序检查正数或负数

任何大于零的数字都是正数，如果小于零，则是负数。这个 Go 程序使用 If else 来检查给定的数字是正数还是负数。如果你看到 If 条件，它会检查用户输入的数字是否大于零。

package main

import "fmt"

func main() {

    var num int

    fmt.Print("Please enter any Integer = ")
    fmt.Scanf("%d", &num)

    if num >= 0 {
        fmt.Println("Positive Integer")
    } else {
        fmt.Println("Negative Integer")
    }
}

SureshMac:GoExamples suresh$ go run positiveNeg1.go
Please enter any Integer = 10
Positive Integer
SureshMac:GoExamples suresh$ go run positiveNeg1.go
Please enter any Integer = -89
Negative Integer
SureshMac:GoExamples suresh$ go run positiveNeg1.go
Please enter any Integer = 0
Positive Integer

Golang 程序检查正数或负数

这个 Golang 程序使用嵌套的 If 条件来检查零以及正数和负数。

package main

import "fmt"

func main() {

    var num int

    fmt.Print("Please enter any Integer = ")
    fmt.Scanf("%d", &num)

    if num > 0 {
        fmt.Println("Positive Integer")
    } else if num < 0 {
        fmt.Println("Negative Integer")
    } else {
        fmt.Println("You have entered Zero")
    }
}

在这个Go 程序中，我们使用嵌套的 For 循环来检查数字是正数、负数还是零。

package main

import "fmt"

func main() {

    var num int

    fmt.Print("Please enter any Integer = ")
    fmt.Scanf("%d", &num)

    if num >= 0 {
        if num > 0 {
            fmt.Println("Positive Integer")
        } else {
            fmt.Println("You have entered Zero")
        }

    } else {
        fmt.Println("Negative Integer")
    }
}

SureshMac:GoExamples suresh$ go run positiveNeg3.go
Please enter any Integer = -55
Negative Integer
SureshMac:GoExamples suresh$ go run positiveNeg3.go
Please enter any Integer = 0
You have entered Zero
SureshMac:GoExamples suresh$ go run positiveNeg3.go
Please enter any Integer = 2
Positive Integer
