    Counting the characters from each word from a text file

    Im trying to read off an input text file that reads ie. "Three happy dogs eat." My goal is to count the total characters and print ONLY that to the screen AND create an output txt file to read like this:

    Three 5
    happy 5
    dogs 4
    eat 3

    I have counted the total characters and created the output file but haven't counted the individual characters of each word.

    so my current output file is:

    Three
    happy
    dogs
    eat

    How can i count and put the number of characters for each word?

    Code:
    /* Include Files */
    #include <stdio.h>
    #include <ctype.h>                                     
    #include <stdlib.h>
    
    #pragma warning(disable:4996)  
    /*that will stop the warning on scanf being deprecated */
    
    /*fx prototypes*/
    int countAll ();
    int getstuff ();
    
    int main( void )
    {
    	
    	getstuff ();
    
    	countAll();
    
     return 0;
    }
    
    /***** fxs *****/
                        
    
    int getstuff( void )
    {
          FILE *infile;
          FILE *outfile;
          int iochar;
          int num = 0;
    
    			outfile = fopen("outtext.txt", "w");
    
         if (( infile = fopen( "cscdata.txt", "r" )) == NULL ) {
              printf( "text couldn't be opened\n" );
              exit( 1 );
         }
    
         while ( !feof( infile )) {                            
                                                           
              while ( isalpha( iochar = getc( infile )))
    
                      putc( iochar, outfile );
    
    		  putc( '\n', outfile );
    
                     ungetc( iochar, infile );                        
                                                          
              while ( isdigit( iochar = getc( infile )))
           
                    putc( iochar, outfile );
            
                    putc( '\n', outfile );
             
                    ungetc( iochar, infile );                       
                                                           
              while ( !isalpha( iochar = getc( infile )) && ( !isdigit( iochar )) && ( !feof( infile )))
              ;
              ungetc( iochar, infile );                        
         }
            
             fclose( infile );
    
    	 fclose (outfile);
    
         return 0;
    
    	 }
    		
    
    int countAll(void)
    {
    	FILE *infile;
    	int c = 0;
    	int count = 0;
    
    	infile = fopen("cscdata.txt", "r");
    	
    	while (c != EOF) 
    	{
    	count++;
    	c = getc(infile);
    	} 
    	
    	printf("number of all characters = %d\n", count);
    	
    	fclose (infile);
     	
    	return 0;
    
    }
    I was thinking of using strlen()? like

    Code:
     while ( isalpha( iochar = getc( infile )))
    
                      putc( iochar, outfile );
    
                      num = strlen( iochar);
                      putc (num, outfile);
    
    		  putc( '\n', outfile );
    
                     ungetc( iochar, infile );
    can anyone point me in the correct way?

    you may use more functions (for get word, for check count, for print message to the screen)

    dat was cool.

    I forgot to mention though that punctuation shouldn't be counted, as well as white spaces.

    if the data file was :

    Three "happy" dogs eat

    the quotes would be counted

    should we throw in an "isalpha" somewhere?

    if getc() gets data character by character, could I jsut put a count after it and fprintf the count?

    Code:
     while ( isalpha( iochar = getc( infile )))
                           putc( iochar, outfile );
    
                           count++
                           fprintf(outfile,"&d", count);
    			   
    		       putc( '\n', outfile );
                   ungetc( iochar, infile );
    i didn't work, but is it possible to do something like this?

    ok. Im still on it.

    adding count apparently didn't work. no matter where I put it. I get a consecutive number for each word: three 1 happy 2 dogs 3 ect...

    I've done fgets instead of getc. that only gave me a whole string by line.

    c.user 's idea was the closest thing, but it included punctuation marks if added to the input data file. I only want to count the alpha-numeric characters from each word. Seems that "fscanf" is too broad and takes in everything, including punctuation and whitespaces...

    I'm still trying if anyone wants to help out.

    Code:
    #include <string.h>
    
    #define MAXWORD  1000   /* maximal length of a word */
    ...   
        char word[MAXWORD];
    
        unsigned long count;
    
        for (count = 0; fscanf(infile, "%s", word) == 1; )
            count += fprintf(outfile, "%s %lu\n",
                         word, CountLetDigLine(word));
        if (count == 0)
            printf("no chars\n")
        else
            printf("number of all characters = %lu\n", count);
    ...
    +

    Code:
    #include <stddef.h>
    
    size_t CountDigitsLine(const char *l);
    size_t CountLettersLine(const char *l);
    
    /* CountLetDigLine:  count how man letters (all case)
                         and digits in l */
    size_t CountLetDigLine(const char *l)
    {
        size_t n;
        
        if (l == NULL)
            return 0;
        n = 0;
        n += CountDigitsLine(l) + CountLettersLine(l);
        return n;        
    }
    
    /* CountDigitsLine:  count how many digits in l */
    size_t CountDigitsLine(const char *l)
    {
        size_t n;
        
        if (l == NULL)
            return 0;
        for (n = 0; *l != '\0'; l++)
            if (isdigit(*l))
                n++;
        return n;
    }
    
    /* CountLettersLine:  count how many letters in l (all case) */
    size_t CountLettersLine(const char *l)
    {
        size_t n;
        
        if (l == NULL)
            return 0;
        for (n = 0; *l != '\0'; l++)
            if (isalpha(tolower(*l)))
                n++;
        return n;
    }
    you can count only one time letters and digits in the word (these do it twice) by write one function which will do that in one if like: if (isalpha(tolower(*l)) || isdigit(*l)) n++; , but I like to make code more independent in its parts
