What does cr mean?

The meaning of cr: 1. "cr" means carriage return in C language; 2. In text processing, "cr" represents the newline character used on the operating system; 3. cr can be used with the symbol " \r" means that its decimal ASCII code is 13 and hexadecimal code is "0x0D".

In C language, cr means carriage return, and in C, it means the character '\r'. The C language is a process-oriented, abstract, general-purpose programming language that is widely used in low-level development. C language can compile and process low-level memory in a simple way.

C language is a high-efficiency programming language that only generates a small amount of machine language and can run without any operating environment support.

• #In text processing, CR, LF, CR/LF are line breaks used on different operating systems Characters.

• Dos and windows use carriage return and line feed CR/LF to represent the next line,

• , while UNIX/Linux uses line feed characters LF to represent the next line. One line,

• Macintosh (MAC OS system) uses the carriage return character CR to represent the next line.

• CR uses the symbol '\r' Representation, the decimal ASCII code is 13, the hexadecimal code is 0x0D;

• LF is represented by the '\n' symbol, the ASCII code is 10, the hexadecimal code is 0x0A.

• So on the Windows platform, line breaks are represented by two bytes of 0d 0a in text files, while on UNIX and Apple platforms, line breaks are represented by one byte of 0a or 0d.

• Generally, the runtime library on the operating system will automatically determine the newline format of the text file. For example, if a program is run on Windows, it will generate a text file in CR/LF newline format, and if it is run on Linux, it will generate Text files with line breaks in LF format.

Using a file with another line break on one platform may cause unexpected problems, especially when editing program code. Sometimes The code displays normally in the editor, but errors occur due to line breaks when editing.

Many text/code editors have a line break conversion function. Use this function to convert line breaks in text files. Symbols are interchangeable in different formats.

Whether in C language or other languages, the definitions of CR and LF will not change, basically as mentioned above.
