[QUOTE="quentisa, post: 1018962, member: 98424"] Please explain how the strtok() method works. According to the documentation, it splits the string into tokens. I can't figure out what it does based on the handbook. [CODE]/* strtok example */ #include <stdio.h> #include <string.h> int main () { char str[] ="- This, a sample string."; char * pch; printf ("Splitting string \"%s\" into tokens:\n",str); pch = strtok (str," ,.-"); while (pch != NULL) { printf ("%s\n",pch); pch = strtok (NULL, " ,.-"); } return 0; }[/CODE] When the first while loop began, the contents of str were merely "this." I added watches on str and *pch to test its functionality. How did the following output appear on the screen? [/QUOTE]
