segfault on 2018-11-01 12:14: It is interesting for a beginner! If it is okay to ask this,is there a stack overflow or something similar?

daniellimws on 2018-11-03 12:36: Hmm there shouldn't be. If something goes wrong please let me know.

segfault on 2018-11-03 17:22: When I pipe huge amount of char to the program,every time I run executable, it tries to input extra characters that are left from initial running.

daniellimws on 2018-11-06 02:15: This is just because the program only reads in a certain amount of bytes. The rest does not get read by the program and so your terminal will read it instead.
