In your edition, it is customary to put the first paragraph in the preview of the article. But the text comes to you in the program as a whole. In order to optimize the process and not copy this paragraph manually every time, you decided to write a small program that takes all the text from standard input (stdin) and displays only one paragraph.
Please note that each paragraph of text in the electronic representation is a separate line. So one must remember the stream input function, which allows you to scan with the newline character
\n as a delimiter.
