Dealing with input in C

问题

A brief question really, looking for, wondering about, and asking for any tips for what the best way is to handle this type of input:

 word word
 word word word word
 word word word
 word word

whereby the number of words on each line is totally random, and each separate word can be added to some data structure, like a linked list or tree for example.

Fgets each line and parse? Getchar()? Any clues?

回答1:

Reading one line at a time with fgets seems like the best option here. Then just use strtok or something similar to split by empty space and iterate over the result.
