Drill down into Windows to enter a carriage return line (\ r \ n) or a newline carriage return (\n\r) of the detailed _c language

Remember to output a carriage return (skip to the beginning of the next line) with 0DH (\ r) and 0AH (\ n) when Windows X86 assembly language. The problem is, under Windows is the first carriage return to change the line or the first line and then enter? Line break on Unix system only \n,mac OS only \ r (said online, no MAC OS, no proof), will not appear above the problem.

Now create a new text document that reads as follows:

It is now read into a string in C-language binary (refer to my article: Drill down into the C language to read the file into a string and write the string to the file) and output in decimal. The results are as follows

You can see that the carriage return is 13 and 10 is the \ r \ n, that is, enter the first line.

Let's take a look at what happens when you swap the \ r \ n between A and B:
