Question

I have a string input which contains words separated by white-space. I want to use sscanf() to split the words, store each word in input_word and print it, but I’m not sure how to put it in a while loop.

This is what I have:

 char input[max];
 char split_input[max];

 /* input gets populated here */

 while (sscanf(input," %s", split_input)) {
     printf("[%s]\n", split_input);
 }

What would be the condition to terminate the loop as soon as the last word in the sequence is split?

Answer 1

you’re using the wrong function there. Might I suggest strtok() instead?
