What is \n newline character?

The new line character is a special character that is used in various programming languages and text files to indicate the end of a line or paragraph. This character is represented by the \n sequence in most programming languages, and is used to create a new line in a file or string.

In the early days of computing, when most text was displayed on a screen or printed on a printer, the new line character was used to create a new line on the display or page. This was necessary because, unlike modern displays and printers, which can automatically wrap text to the next line, early displays and printers could only display one line of text at a time. The new line character was first introduced in the 1960s, and has been a staple of text-based computing ever since. It is still used in many programming languages and text files today, and is an essential part of any programmer's toolkit.

One of the most common uses of the new line character is in the creation of text files. When a text file is created, it is typically divided into multiple lines of text, each separated by a new line character. This makes it easier for the user to read the file, and allows for more efficient processing by the computer.

For example, if we were to create a text file containing a list of names, each name would be placed on a separate line. This would allow us to easily search for a specific name in the file, or to sort the names alphabetically. Without the new line character, the entire list of names would be displayed on a single line, making it much harder to read and process.
