why "" when inputing \n

Question

i was wondering why i need to put \n in "" and not just a plain break?

Answer 1

Because you are sending a newline character which must be processed as part of a string. *Note* you can also use endl for the same result.

Example:

std::cout << "Hello World" << endl << "This is on a new line";

This is the same as

std::cout << "Hello World\nThis is on a new line";
