ring buffer - overwrite function - Correct code link this time.

I am having issues with the overwrite function of the circular buffer file. It keeps returns an empty buffer on some test runs. What am I missing? https://code.sololearn.com/cpBWFOKyi6mL

I guess by " returns an empty buffer on some test runs" you are referring to the read operation after an overwrite. I reckon, overwrite means to be able to write despite a full buffer. In that case I suppose you need to advance the read head should read == write after the write operation. Otherwise, if you look at your condition in read, read == write will be interpreted as empty buffer. Note, however, only to advance the read head if the write operation actually does overwrite the current read head.

You're welcome 🙂 What test sets are you testing against? đŸ€” That does not look like some competetive programming task đŸ€”

Ani Jona: I am learning using Sololearn, Exercism, codewars and books. The test set for this exercise was from: Exercism's Unity test. https://exercism.org/tracks/c/exercises/circular-buffer I'm not competitive just trying to learn on my own. My background is in DOD HR not CS.
