Strings with blank convert to bytes

[洪嘉鴻]

Hello everyone:

I use golang with Win10. The version of golang I used is go1.12.9.

This is a simple code I'm trying to figure out.

However, I have no idea how to edit to make the output "b1" the same as "b" if "b1" is read from user input.

Could anyone help me to solve this problem?

Any help is appreciated.

Thank you very much!

Hello!

Just quote the document:

> Scanf scans text read from standard input, storing successive space-separated values into successive arguments as determined by the format

Instead, you can use fmt.Scanln.

Hello!

The problem isn't solve when I use "fmt.Scanln" instead of "fmt.Scanf".

That is, the result is the same whatever I use "fmt.Scanln" or "fmt.Scanf".

Thanks for your replying.

From the documentation:

the %s verb (and %v reading into a string) stops consuming input at the first space or newline character.

You shouldn't be using the Scanf family of functions if you don't want the input split on whitespace boundaries. You probably want bufio.ReadLine or similar. See https://stackoverflow.com/questions/8757389/reading-a-file-line-by-line-in-go

 

Instead, you can use fmt.Scanln.

Hello!

I've just found this according the information which you provided.

Although there is a little different that it also reads "\n" with ReadString().

However, it solves my problem.

Thanks for your replying.
