Not getting proper output

Question

package main

import "fmt"

func scale(num int,factor *float32){

}

func main() {

    var num int

     var factor float32

    fmt.Scanln(&num)

    fmt.Scanln(&factor)

    scale(num, &factor)

    fmt.Println(num)

}

Answer 1

Looks like you wrote the code on another platform and paste it here.
Try deleting it and rewrite on code playground

Answer 2

I just removed the invalid characters from your code.
Can I see the task what you're trying to do?
I mean copy the task and paste it here

Done Simba thanks buddy

Answer 5

package main
import "fmt"

func scale(num *float32, factor float32){
*num *= factor
}

func main() {
var num float32
var factor float32

fmt.Scanln(&num)
fmt.Scanln(&factor)

scale(&num, factor)
fmt.Println(num)
}

Answer 7

Simba not getting the actual output. Where I am wrong can u plz make me understand.

Answer 8

The solution of Scale Factor Code Coach is

package main
import "fmt"

func scale(x *float32, y *float32){
*x*=y
}
func main() {
var num float32
var factor float32

fmt.Scanln(&num)
fmt.Scanln(&factor)

scale(&num, factor)
fmt.Println(num)
}

Here, in the main() function, when the scale function is called with arguments, &num passes the memory address of the value, and factor is a direct value.
Now, in function scale, the parameters are passed as x *float32 because it can retrieve the value from the memory address and put it into the calculation.
Also, the actual arguments passed in the scale function are both float32.
