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]); 
}
