Side note : If you are using nextInt() with nextLine() you probably could have some trouble cause nextInt() does not read the last newline character of input and so nextLine() then is not gonna to be executed with desired behaviour.

The cin.clear() clears the error flag on cin (so that future I/O operations will work correctly), and then cin.ignore(10000, ‘\n’) skips to the next newline (to ignore anything else on the same line as the non-number so that it does not cause another parse failure). It will only skip up to 10000 characters, so the code is assuming the user will … Read more
To read user input you can try the cmd module for easily creating a mini-command line interpreter (with help texts and autocompletion) and raw_input (input for Python 3+) for reading a line of text from the user.

Depending on the operating system, this character will only work if it’s the first character on a line, i.e. the first character after an Enter. Since console input is often line-oriented, the system may also not recognize the … Read more
The reason is that php://input returns all the raw data after the HTTP-headers of the request, regardless of the content type. The PHP superglobal $_POST, only is supposed to wrap data that is either application/x-www-form-urlencoded (standard content type for simple form-posts) or multipart/form-data (mostly used for file uploads) This is because these are the only content types that must be supported by user agents. … Read more

The conio.h header is specific to Turbo C, which predates the earliest C standard by several years. It contains routines that are specific to the DOS command line. One function here that’s frequently used is getch, which allows reading one character at a time without having to press the Enter key. It also contains gotoxy which allows placing … Read more
