But there is a problem, that is, when a line breaks a line, it takes 0.2 seconds, just two characters. If a new character is passed in the 0.2 s, the character will be lost.

One is called "carriage return", which tells the typewriter to position the printhead at the left border, and the other is called "line break", telling the typewriter to move the paper down one line. This is the origin of "line break" and "carriage return", from their English name can also be seen in one or two. Later

Summary of \ r and \ n \ R indicates carriage return and \ n indicates line feed. In Windows, the input key will automatically become \ r \ n. In Windows, \ r \ n is also required for line breaks. Why do we need two characters? Because Windows adopts the traditional typewriter model, there is a small story: Before the computer appeared, there was a kind of device called Teletype Model 33, which can contain 10 characters per second. But there is a prob

---- Start Many people cannot figure out what is carriage return and line feed. The following briefly introduces the origins and differences of these two concepts. Before the advent of a computer, there was a kind of thing called a telex typewriter that allowed 10 characters per second. But there is a problem, that is, when a line breaks a line, it takes 0.2 seconds, just two characters. If a new character is passed in the 0.2 s, the character will be

problem by adding two characters to the end after each line. One is called "carriage return", which tells the typewriter to position the print head at the left edge, and the other is called "line-wrapping", telling the typewriter to move the paper down one line. This is the "line" and "return" of the history, from their English name can also be seen in one or two. Later, the computer was

The difference between Linux and Windows return line break source of the problem: "Carriage return" (carriage return) VS "line feed"Before the computer appeared, there was a gadget called a telex typewriter (teletype Model 33) that could play 10 characters per second. But it has a problem, that is, when the line is finished, it will take 0.2 seconds to hit two characters. If there are new characters coming in this 0.2 seconds, then this character wil

The origins and differences between the two concepts of carriage return "(carriage return) and" line feed ".Before the computer appeared, there was a thing called a telex typewriter (the concept of TTY under the teletype Model 33,linux/unix), which can be played 10 characters per second.
