What is the purpose of the fflush() function?
Answer: A
Correct answer: flushes all streams and specified streams
fflush(fp) writes out the buffer of one stream; fflush(NULL) flushes every output stream. It matters because output is buffered: without a flush, text may still be sitting in memory when a program crashes. (fflush on an input stream is undefined behaviour, despite being widely misused.)
