c clear buffer

To clear the buffer in the C programming language, you can use the fflush() function. The fflush() function is typically used to flush a stream, which means it clears any data that may be present in the stream's buffer and writes any remaining data to the underlying file.

Here are the steps to clear the buffer using fflush():

1. Identify the stream you want to clear the buffer for. This can be the standard input stream stdin, standard output stream stdout, or standard error stream stderr.

2. Call the fflush() function and pass the stream as its argument. For example, to clear the buffer for the standard input stream stdin, you would use fflush(stdin).

3. The fflush() function will clear the buffer for the specified stream and ensure that any remaining data is written to the file. Note that fflush() does not clear the entire input buffer, but rather discards any unread characters.

By following these steps and using the fflush() function, you can effectively clear the buffer in the C programming language.
