A simple program in Go to determine how many layers of clothing do I need and a convenient ºC to ºF converter

main.go

package main

import (
  "fmt"
  "strconv"
)

func calculate (inpt string) {
  a, _ := strconv.ParseFloat(inpt, 64)
  if (a < 15 && a >= 10) {
    fmt.Println("one thin layer")
  } else if (a < 10 && a >= 5) {
    fmt.Println("two thin layers or a thick layer")
  } else if (a < 5 && a >= 0) {
    fmt.Println("two thick layers or a snow jacket")
  } else if (a < 0) {
    fmt.Println("snow jacket and another layer")
  }
  cToF(a)
}

func cToF (c float64) {
  f := (c * 9 / 5) + 32
  fmt.Printf("it's %f degrees Farenheit\n", f)
}

func main() {
  fmt.Print("value: ")
  var inpt string
  _, err := fmt.Scanf("%s", &inpt)

  if err != nil {
    fmt.Println(err)
  }

  calculate(inpt)
}
