The newline character ('\n') is used to move the cursor to the beginning of the next line. It is the most commonly used method for creating line breaks in C++ output because it does not automatically flush the output stream.

Unlike std::endl, the newline character simply inserts a line break and allows the output stream to continue buffering data. This generally provides better performance, especially when producing large amounts of output.

Source Code #

#include <iostream>

int main()
{
    std::cout << "First Line\n";
    std::cout << "Second Line\n";
    std::cout << "Third Line\n";

    return 0;
}

Output #

First Line
Second Line
Third Line

Explanation #

• '\n' is the newline escape character used to move the cursor to the next line.
• The newline character can be included directly inside a string literal or inserted separately into the output stream.
• Unlike std::endl, '\n' does not flush the output stream after printing the newline.
• Since the output buffer is not flushed automatically, using '\n' is generally more efficient for normal output operations.
• The newline character is suitable for most console programs where immediate output is not required.
• std::cout writes the text to the standard output stream.
• return 0; terminates the program successfully.
