    Read single words seperated by white space in as strings

    I am trying to read from a text file, and have each word become a new string. Is fgets a bad weapon of choice? It reads until a \n character, I guess I need to read until ' '?

    Code:
    LIST *CreateList(FILE *fp)
    {
       char buf[BUFSIZE];
    
       fgets(buf, 256, fp);
       puts (buf);
    
    
    } /* End CreateList */

    i think fgets automatically puts a null character at the end of the file.

    what if you tried

    Code:
    #define BUFSIZE 256
    
    char buf[BUFSIZE + 1];
    
    fgets(buf, BUFSIZE + 1, fp);
       
    puts (buf);

    Sure, use fgets to get the whole file/line. It is safe:

    From man-page
    fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an EOF or
    a newline. If a newline is read, it is stored into the buffer. A '\0' is stored after the last character in the buffer

    then use strtok to get the words in separate strings.
