Go Program to Print Positive Numbers in an Array

This Go program to Print Positive Numbers in an Array uses for loop to iterate user-entered array items. Within the for loop (for i = 0; i < posize; i++), the if condition (if posArr[i] >= 0) checks whether the number is greater than or equal to zero. If True, it is a  Positive number, so print it.

package main

import "fmt"

func main() {
    var posize, i int

    fmt.Print("Enter the Positive Array Size = ")
    fmt.Scan(&posize)

    posArr := make([]int, posize)

    fmt.Print("Enter the Positive Array Items  = ")
    for i = 0; i < posize; i++ {
        fmt.Scan(&posArr[i])
    }

    fmt.Print("\nThe Positive Numbers in this posArra = ")
    for i = 0; i < posize; i++ {
        if posArr[i] >= 0 {
            fmt.Print(posArr[i], " ")
        }
    }
    fmt.Println()
}

Enter the Positive Array Size = 5
Enter the Positive Array Items  = -22 0 -9 14 11

The Positive Numbers in this posArra = 0 14 11 

Go Program to Print Positive Numbers in an Array using For Loop Range

package main

import "fmt"

func main() {
    var posize int

    fmt.Print("Enter the Positive Array Size = ")
    fmt.Scan(&posize)

    posArr := make([]int, posize)

    fmt.Print("Enter the Positive Array Items  = ")
    for i := 0; i < posize; i++ {
        fmt.Scan(&posArr[i])
    }

    fmt.Print("\nThe Positive Numbers in this posArra = ")
    for _, po := range posArr {
        if po >= 0 {
            fmt.Print(po, " ")
        }
    }
    fmt.Println()
}

In this Golang program, we created a (printPositveNum(posArr []int)) function to print Positive array numbers.

package main

import "fmt"

func printPositveNum(posArr []int) {
    fmt.Print("\nThe Positive Numbers in this posArra = ")
    for _, po := range posArr {
        if po >= 0 {
            fmt.Print(po, " ")
        }
    }
}
func main() {
    var posize int

    fmt.Print("Enter the Positive Array Size = ")
    fmt.Scan(&posize)

    posArr := make([]int, posize)

    fmt.Print("Enter the Positive Array Items  = ")
    for i := 0; i < posize; i++ {
        fmt.Scan(&posArr[i])
    }
    printPositveNum(posArr)
    fmt.Println()
}

Enter the Positive Array Size = 10
Enter the Positive Array Items  = 1 0 -99 8 -66 -55 2 125 -67 220

The Positive Numbers in this posArra = 1 0 8 2 125 220
