Solution Review: Temperature Conversion

Understand how to use Go's type aliases to represent Celsius and Fahrenheit temperature types. Learn to write a conversion function applying the standard formula and practice calling it in a main program. This lesson helps build foundational skills in Go function creation and type management.

We'll cover the following...
Go (1.6.2)
package main

import (

	"fmt"

)



// aliasing type

type Celsius float32

type Fahrenheit float32



// Function to convert celsius to fahrenheit

func toFahrenheit(t Celsius) Fahrenheit {

	return Fahrenheit((t*9/5 )+ 32) 

}



func main() {

    var tempCelsius Celsius = 100



	tempFahr := toFahrenheit(tempCelsius)	// function call

    fmt.Printf("%f ˚C is equal to %f ˚F",tempCelsius,tempFahr)

}

  • Lines 7-8: We aliased the types of the temperature, i.e., float32 to Celsius and Fahrenheit. At line 7, we alias the type float 32 by giving the name Celsius. We need another type called Fahrenheit, ...
