endl vs \n in C++
  • Difficulty Level : Easy
  • Last Updated : 08 Feb, 2021

Although they both seem to do the same thing, there is a subtle difference between them. 

cout << endl  : Inserts a new line and flushes the stream

cout << "\n"  : Only inserts a new line.

cout << endl; 
can be said equivalent to 
cout << ‘\n’ << flush; 
So cout << “\n” seems performance wise better than cout << endl; unless flushing of stream is required. 
Some other differences between endl and \n are:  

  1. endl is manipulator while \n is character.
  2. endl doesn’t occupy any memory whereas \n is character so It occupy 1 byte memory.
  3. \n being a character can be stored in a string(will still convey its specific meaning of line break) while endl is a keyword and would not specify any meaning when stored in a string.
  4. We cannot write endl in between double quotation while we can write \n in between double quotation like 
    cout<<“\n”; it is right but cout<<“endl”; is wrong.
  5. We can use \n both in C and C++ but, endl is only supported by C++ and not the C language.
