I have a question. I am learning C programming and while reading and storing user input into a char array I came across this code. Can someone explain to me what the "\r" mean? Thank you

arr[strcspn(arr, "\r\n")] = 0;

CodePudding user response：

\r is ASCII character 13, called "CR" or "carriage return".

Unix traditionally used \n (ASCII character 10, LF, line feed) as the end of a line, but Windows traditionally uses \r followed by \n (note that a lot of Windows functions do convert it to just \n). So to detect both, you can check for both \r and \n.

CodePudding user response：

As user253751 suggested it is the carriage return.

To give some more context, there are the most important escaped character sequences related to new line, spaces etc..

Hope it is helpful!
