Requesting help with the code

[Kareem Shaikh]

Hi All,

Good Afternoon.

My name is Kareem. 

I recently started learning GO on my own.

I am going through the book "INTRODUCTION TO GO" from RIELY.

I wrote a program to convert Degrees to Fahrenheit. It is as follows:

package main

import "fmt"

func main () {

  fmt.Println("Enter the degrees to convert into farenhiet: ")

  var Degrees float64

  fmt.Scanf("%f", &Degrees)

  var farenhiet float64

  farenhiet = ((Degrees*9)/5) + 32

  fmt.Println("&Degrees Degrees to Farenhiet is = ", Degrees, farenhiet)

}

In th last statement " fmt.Println("&Degrees Degrees to Farenhiet is = ", Degrees, farenhiet)" I wanted to print the value of the degrees and then the result.

I am struggling with this. 

Can anyone please tell me what should I change in order to get the right output?

For example:

I want to change 10 degrees to Fahrenheit.

I want to print "10 degrees to Fahrenheit is = 50"

Please help me with the code to print the exact line that I want.

I understand I can write the same statement as above but what I want exactly is that we never know what number(degrees) we input.

So please help me modify the code as per my requirement.

PS: Please help me with any books to read after the above mentioned book. 

Thank You.

You want to use one of the formatting functions, for example:

fmt.Printf("%f Degrees to Fahrenheit is = %f\n", Degrees, fahrenheit)

For more information, see the fmt documentation: https://godoc.org/fmt

That's how I would do it. But you can also use fmt.Println, just change the order:

fmt.Println(Degrees, "to Farenhiet is =", farenhiet)

Kareem,

Here is an example,

package main

import "fmt"

func main() {

    fmt.Println("Enter degrees Celsius (℃): ")
    var celsius float64
    fmt.Scanf("%f", &celsius)
    var fahrenheit float64
    fahrenheit = ((celsius * 9) / 5) + 32
    fmt.Printf("%.2f℃ is %.2f℉\n", celsius, fahrenheit)
}

Output:

Enter degrees Celsius (℃):
10
10.00℃ is 50.00℉

See package fmt: https://golang.org/pkg/fmt/

Thank You Peter.

I will try this.

Could you please let me know which are the subsequent books to follow for learning GO after "Introducing GO"?

Hi Jake,

This works.

Thank You very much.

Could you please let me know which books should I follow to learn GO after completing "Introducing GO"?

If you haven't gone through "A tour of Go", I'd suggest it - it is pretty practical and helpful in learning the language:

https://tour.golang.org/welcome/1

"Go by Example" has a bunch of good resources too for practical use:

Hope this helps!

Bob
