It assumes that the file it is reading is a text file and that lines in this text file are no longer than 16384 (or {LINE_MAX} if it is less than 16384 on the implementation where it is running) bytes long. but i still can't figure how to fill a 2-d array using fgets without overwriting the buffer when i use fgets mulitple times.

Sample Input: @ON S When you then get to fgets it will read anything up to the first newline character, which in this case is nothing at all as the first thing fgets sees is the newline left there by scanf. It‘s one of the core input functions included in the vast majority of C standard libraries and toolchains. It stores the input into a character array and stops reading when it reaches a newline character, the specified number of characters, or end-of-file (EOF). Hence it is highly recommended over the gets() function. Apr 16, 2016 · I am having trouble using fgets() and strtok() to receive an input and splitting them up accordingly.
