Simple C program to count word lengths

So my program is not working and I keep changing it to figure out why. So I have two questions, can I do tracing similar to bash, and also what is wrong with this.

The idea is simple, I want to count "word" lengths, with the loose definition of word not being a space, tab, or newline. Here is what I wrote to test if it is counting words by outputting the number of 3 letter words, but it always gives 0.

Code:

#include <stdio.h>

main() {

     int c, i, state, wl;
     int maxlength[15];

     #define IN 1
     #define OUT 0

     wl = i = c = 0;
     state = OUT;
    
     for (i=0; i < 15; ++i)
          maxlength[i] = 0;

     while ((c = getchar()) != EOF) {
          if (c == ' ' || c == '\t' || c == '\n') {
               if (state == OUT)
                    ;
               else if (state == IN) {
                    state == OUT;
                    ++maxlength[wl];
                    wl = 0;
               }
          else { 
               ++wl;
               state = IN;
          }
          }
     }
     printf("Number of 3 letter words: %d\n", maxlength[3]); 
}

vlatai(1L)																vlatai(1L)

NAME

       vlatai - Lojban word analyzer

SYNOPSIS

       vlatai [ -v ] [ word ]

DESCRIPTION

       vlatai is a program that reads a list of Lojban words from standard input, one word per line.  In its usual mode, it writes a single output
       line for each input line, advising of which kind of Lojban word the input line is.   If the input word has cmavo prefixed onto  it,  vlatai
       shows the individual cmavo and the base word itself.

       In the verbose mode (obtained using -v), the workings of the internal state machines used for scanning the word are exposed.  This may give
       some insight into where an error lies on words that can't be parsed, especially if the output is used in conjuction with the  report  files
       built during the compilation process.

       Note that vlatai is primarily a testbench for the word categorizer/splitter inside jbofihe.  vlatai is not fully supported or documented as
       a stand-alone program.

OPTIONS

       -v     Verbose; show lots of information about the evolution of the internal state

       word   The word to check.  If no 'word' argument is supplied, the program reads words from standard input,  one	word  per  line  (with	no
	      whitespace around it.)
