Last updated on: .


There are some characters in C++ that we can’t enter into a program directly from the keyboard.

For example:

■ In C++ we can’t make a newline by pressing the Enter key.
Instead we have to use a code in our source code file for the new line.

■ We can’t put Double Quotation Mark in the middle of a string literal like the following example:

cout << "We are from "India" " << endl;

To solve this problem we have to use Escape Sequence.

The right example is:

cout << "We are from \"India\" " << endl;

◕ What are the codes for a New line?

- We can use three types of code for a new line.

These are:

■ cout << endl; // using the endl manipulator

■ cout << '\n'; // using the '\n' character constant

■ cout << "\n"; // using the "\n" string

All three of the above codes move the cursor to the beginning of the next line.

◕ Where we should use endl or '\n'?

- When we use number, then endl is easier to use for new line.

- When we use a longer string, then '\n' is often more convenient than using endl.

Examples are given bellow:

cout << "Enter a number:" << endl;
cout << "\n\n We are Indian. \n We are proud to be an Indian. ";
