    read string with fgets followed by another string needed to read

    Hey guys, another question that someone might know. I have to read a line containing three string sets needed for data of my program. However, the different strings are seperated by different amounts of whitespaces /tabs and the middle string can actually consist of several "strings" as it is the boat name. I have no idea how to go about it, as I keep thinking that if I use fgets() and find the first string, I d loose the seconds string. --> since i dont know how many whitespaces are leading the first string and cant therefore set the chars to read for a particular purpose.
    Any help is really appreciated.
    Cheers,
    Johannes.

    Attached is a sample file we were given for the assignment.

    Cheers.

    Try something like this...

    Code:
    int main()
    {
      char inputString[MAX_STRING_SIZE];
      char stringOne[MAX_STRING_SIZE];
      char stringTwo[MAX_STRING_SIZE];
      char stringThree[MAX_STRING_SIZE];
    
      /* read long string from file into inputString[] */
    
      /* search forward for start of first word (first non-white space) */
    
      /* search forward for end of first word (next white space) */
    
      /* copy data between the two points into stringOne */
    
      /* search back for end of 3rd word (last non-white space) */
    
      /* search back for start of 3rd word (next white space) */
    
      /* copy data between two points into stringThree */
    
      /* stringTwo lies between endStringOne and startStringThree */
      /* minus the white space - find start and end */
    
      /* copy data between two points into stringTwo */
    
      return 0;
    }
    I'll leave you to fill in the gaps
