Can \n is used only inside string of cout ?

Answer 1

It's used in strings but not only when you output string on console with cout , it's also used when you write data to files.

in case you don't know what is mean by writing in files:
we do something like this :

fstream myfile("data.txt",ios::out);
//creates object of file stream classs and opens a file named data.txt in write mode to output something in it

myfile<<"This is my text \n in my file ";
//writes text in file on two different lines.

myfile.close();
//close file so resources are available for other tasks..

If you don't understand this don't worry . focus on what you are learning. you'll understand this sooner.

anyone know where else it's used? please let me know.
