go - How to check if Scanln throws an error in Golang -

I am new to go. I was searching for answers and I know that there is really one that I have have not received.

To better explain my question, this is my code:

  func main () {... inputs: = new (inputs) fmt.println ("Input two numbers:") fmt.Scanln (& inputs.A) fmt.Scanln (and inputs.B) fmt.Println ("sum:", inputs.A + inputs.B)}  < / Pre> 
 And here is my straight: 
 
  Type input structure {A, B int}  
 
 If I input to input A ' 123 'and the second' 123 'for input B, I have an output of "  is sum: 246  " But if I accidentally input  '123j' , then it will not work anymore because A and B only accept the int (s). 
 
 Now, how can terror hold with  fmt.Scanln  or any other way? thank you in advanced.

You are ignoring two important return values. Scan and count of fault .. If there was one.

  n, err: = fmt.Scanln (and inputs.A)  

... will tell you what to check. mistake will tell you that a new line was expected and it was not found because you tried to store the value in int .. and it
