        tavim++;

printf("total chars: %d", tavim);
printf("total words: %d", words);
printf("total lines: %d", lines);
printf("total numbers: %d", numOfDig);
printf("total Letters: %d", numOfLet);
printf("total whitespaces: %d", whitespaces);
return 0;

}

I just wanna check if its alr

how are you counting words? as it is, you'll count every character from the first instance of anything that matches isLetter() or isDig() until the end of the program as a new "word", which i doubt is what you want. the easiest thing to modify your current program to actually count words might be a rising edge detector -- that is, an if statement that is true if and only if wordy was 0 on the previous iteration of the loop, and is now 1 on the current iteration of the loop

also, might i suggest <ctype.h>? it has the functions isspace() (an analogue for your isWhite() function that also checks for tabs), isalpha() (a near-direct replacement for your isLetter() function), isdigit(), etc

oh, the reason that pressing ctrl+D didn't work is that you're doing ch == getchar(). in this case you want the single equals, not the double equals, and even then you'll still have to press ctrl+D twice

not quite sure how you'll manage to detect the first ctrl+D using just getchar(), though

[shy nebula]

btw, getchar returns an int not a char

[shy nebula]

isspace checks for different characters then their isWhite function

[shy nebula]

you can change if(...){return true;}else{return false;} to just return ...;

[dapper linden]

nah we need to do the whole checks and stuff ourselvese (its homework
