What does /n mean in c++

/n in C represents a newline character

In the C programming language, the \n escape sequence represents a newline character.

Purpose

The newline character is used to move the text content to a new line. It is often used with output operations such as cout to create new lines in the output.

Representation form

In C, the newline character can be represented in the following two ways:

• Character constant: '\n'
• Escape sequence: "\n"

Usage examples

Consider The following code snippet:

<code class="cpp">#include <iostream>

using namespace std;

int main() {
  cout << "Hello" << endl;
  cout << "World!" << endl;
  return 0;
}</code>

In this example, the endl stream manipulator (essentially a special string stream containing newlines) is used between "Hello" and "World!" " Create new lines between output statements.

The output result is:

<code>Hello
World!</code>

Note

• In the Windows operating system, the newline character is usually represented as "\r\n" , where "\r" is the carriage return character. In other operating systems, such as Unix and macOS, just use "\n".
• In C, you can also use the '\r' escape sequence to represent a carriage return character, which moves the cursor to the beginning of the line without wrapping.
