Golang : Test a slice of integers for odd and even numbers

Got this question from one of my students and he is from a disadvantaged background(he is a refugee). He wanted to know how to accept a line of integers and test each of the numbers to see if they are odd or even. Below is a simple program that can do just that.

NOTE: Sometimes things that we take for granted can be so exciting and fascinating for those that don't have this "luxury" in their life. Luxury such as able to touch a computer, go online and learn to program in a safe environment.

 package main

 import (
  "bufio"
  "fmt"
  "os"
  "strconv"
  "strings"
 )

 func main() {

  fmt.Print("Enter a number to test if odd or even : ")
  //fmt.Scanf("%d", &num)

  numberReader := bufio.NewReader(os.Stdin)
  num, _ := numberReader.ReadString('\n')

  // the input can be multiple integers with spaces in between
  // turn to slice

  numSlice := strings.Fields(num)

  for _, v := range numSlice {
 i, _ := strconv.Atoi(v)
 if i%2 == 0 {
 fmt.Println(v, "is Even")
 } else {
 fmt.Println(v, "is Odd")
 }
  }
 }

Sample input and output:

$ go run oddeven.go

Enter a number to test if odd or even : 1 2 3 4 5 6 7 8 9

1 is Odd

2 is Even

3 is Odd

4 is Even

5 is Odd

6 is Even

7 is Odd

8 is Even

9 is Odd

$ go run oddeven.go

Enter a number to test if odd or even : 99 98 97 96 55 33 1

99 is Odd

98 is Even

97 is Odd

96 is Even

55 is Odd

33 is Odd

1 is Odd

May you learn enough from me to have a better life :-)
