When fscanf in golang reads a file, replace the carriage return with 0

First, you must understand the working principle of Fscanf:

Fscanf ends when it encounters \n. When it encounters \r, it will replace \r with 0.

Question:

There is a problem. You should pay attention to the newline character of your text. Under Windows, it is \r\n. Under Linux and Mac, it is \n, that is. Said there was a pit here.

It is normal for the code to read data files under Linux and Mac. Under Windows, you will encounter 0 at the end of various lines.

Solution:

Just use the built-in IDE to change the newline character of the opened data file set to LF (Linux, Mac newline character).

As shown below:
