How to use /n in c++

The newline character in C is \n, which is used to move the cursor to the beginning of the next line. You can: Output the newline character: Use std::cout to output \n to the console or file. To include a newline character in a string: use the escape sequence \n. Reading newline characters: Use std::getline() to read a line of text from the input.

Using newlines in C

In C, \n is a newline character, used to move the cursor to the beginning of the next line. It can be generated by the escape sequence '\\n'.

Usage:

• Output newline character: Use std::cout to \n Output to console or file. For example:

std::cout << "Hello" << std::endl;  // 输出 "Hello" 并换行

• To include a newline character in a string: can be included in a string using the escape sequence '\\n' Newline character. For example:

std::string str = "Hello\nWorld";  // 字符串包含一个换行符

• Reading newlines: You can use std::getline() to read a line of text from the input, including newlines symbol. For example:

std::string line;
std::getline(std::cin, line);  // 从标准输入读取一行文本

Other line breaks:

In addition to \n, C has the following line breaks:

• \r: carriage return character. Moves the cursor to the beginning of the current line without wrapping.
• \r\n： Carriage return and line feed character. Used in Windows systems to perform carriage return and line feed operations simultaneously.

Note:

• The exact behavior of newlines depends on the operating system.
• When reading text using std::getline(), line breaks are usually automatically removed.
• When using newline characters in cross-platform code, it is recommended to use the std::endl macro, which can automatically handle the differences in newline characters in different operating systems.
