    no worries...i figured it out... code below

    Code:
    int fileLength(FILE *file) {
    
    	int file_len=0;	
        char line[LINESIZE];
    	char *linePtr = line;
    
            while (fgets(line, LINESIZE, file) != NULL) {
    
    			while(*linePtr != '\0') {
    				
    				/* move through non words */
    				while((isspace(*linePtr)) || (ispunct(*linePtr)))
    					linePtr++;
    				
    				/* reached a word */
    				file_len++;
    				linePtr++;
    
    				if(*linePtr == '\0')
    					break;
    				
    				/* move off the word */
    				while(isalpha(*linePtr))
    					linePtr++;
    
    			}
    		}
    		printf("\nFile Length:%d", file_len);
    		return file_len;
    }

    You need
    lineptr = line
    each time you start the loop
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
