Carriage Return and line feed "\ r \ n" in Windows"

"\ R \ n"

In Windows:
'/R': Press enter to return to the beginning of the current row, instead of the next row;
'/N' line feed, switch to the next line at the current position, instead of returning to the first line;

The origins and differences between carriage return and line feed.
Before the computer appeared, there was a kind of device called teletype model 33, which also came from the TTY concept in Linux/Unix. It can contain 10 characters per second. But there is a problem, that is, it takes 0.2 seconds to finish a line break. It can be two characters long. If a new character is passed in the 0.2 s, the character will be lost.
As a result, the developers thought of a way to solve this problem, that is, adding two end characters after each line. One is "enter", which tells the typewriter to position the print head on the left boundary, and the other is "line feed", which tells the typewriter to move the paper down one line. This is the source of "line feed" and "Carriage Return". They can also be seen in their English names.

Later, computers were invented, and these two concepts were invented on computers. At that time, memory was very expensive. Some scientists thought it would be too waste to add two characters at the end of each line. Just add one character. As a result, there were differences.

In Unix systems, each line ends with only "<line feed>", that is, "/N". In Windows systems, each line ends with "<line feed> <car return> ", that is, "/n/R". In MAC systems, the end of each line is "<press enter>", that is, "/N ";. One direct consequence is that if a file in UNIX/MAC is opened in windows, all the text will be changed to a line; if a file in Windows is opened in UNIX/MAC, A ^ m symbol may be added at the end of each line.

C LanguageProgramming (Windows)

/R means return to the beginning of the row. This overwrites the previous output of this row.

For example:
At last, only Xixi is displayed, and hahaha is overwritten.

Int main ()
{
Cout <"HAHAHA" <"/R" <"Xixi ";
}

/N is the carriage return + line feed, move the cursor first to the beginning of the line, and then switch to the next line, that is, pull the first line of the next line

Int main ()
{
Cout <"HAHAHA" <"/N" <"Xixi ";
}
