The origins and differences between carriage return and line feed. Not on the computerBefore the appearance, there was a teletype Model33. The tty concept in Linux/Unix also comes from this). It can contain 10 characters per second. However, the problem is that it takes 0.2 seconds to finish a line breakIt 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 e

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". T

Line feed(\ N)That is, move the cursor down a line but not move it to the beginning of this line. Press ENTER(\ R)Is to return to the beginning of the current row but not move down a row. Press enter to execute\ N \ rIn this way, we can see the general meaning of the carriage return, so we can use a hexadecimal file to view a text, and we will find it at the end of the line"\ N \ r".

Some time ago, I transplanted a program in Windows to VxWorks. Because the original program needs to read the configuration file Put them together in nor flash, so it's hard to handle compilation errors. When a program is run, an error occurs and debugging is performed, I found all the information I read was wrong !! No, let's take a closer look. The fopen string is like this: "First Line \ R \ nsecond line \ r \ n... ", and then read it in Vs, but it is like this:" First line \ nsecond Line \ n

The typewriter, which was invented at that time, was a solid cylinder + a chrysanthemum-like font. The paper is firmly fastened to the surface of the cylinder. When we press a letter, the mechanical device "fly" to the paper, while the ribbon before the cylinder rises, hard to print, so th
