Your mission

Read the stream f to its end and report how many newlines, words and bytes it holds.

See it in action

stream_count on a stream holding "hello world"

lines=0 words=2 bytes=11

stream_count on a stream holding "one two\nthree\n"

lines=2 words=3 bytes=14

stream_count on an empty stream

lines=0 words=0 bytes=0

Your checklist

• Read f until the end of the stream. Any byte value from 0x00 to 0xFF can appear in it.
• Store in *lines the number of '\n' bytes.
• Store in *words the number of words. A word is a maximal run of bytes that are none of ' ', '\t', '\n', '\v', '\f' and '\r'.
• Store in *bytes the number of bytes read.
• Write all three counters on every call, including when they are 0.
