c - read an unknown number of lines -

i need implement in c programme ,which reads unknown number of lines stdin. know maximum number of lines 100. tried utilize gets ,but don`t know when stop loop. can advise me how implement it?

this depends on when want programme stop. there several mutual approaches:

never: run infinite loop until end-user hits ^c or otherwise terminates programme using facilities of operating system until user enters special marker, i.e. "keyword" quit, exit, etc. on line itself until user enters empty line (i.e. hits enter)

since max number in case 100, can utilize limit automatically terminate input 1 time max reached.

c input stdin gets

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
