Question

I am trying to make a code in C that reads all of the words typed, makes them lower case, and counts how many times the word was typed in. I have a code but it is not counting the amount of times the word was typed in properly.

#include
#include
#include
#define MAXW 500
#define MAXC 50

int main(void) {
   char word[MAXC + 1], list[MAXW][MAXC + 1];
   int n, i, j, k, count[100000]={1};
   setvbuf(stdout, NULL, _IONBF, 0);
   n = 0;
   printf("Enter text with EOD to mark end: ");
   while (1) {
       scanf("%s", word);
       if (0 == strcmp("EOD", word))
           break;
       if ('A' <= word[0] && 'Z' >= word[0])
           word[0] += 'a' - 'A';
       for (i = 0; i <= n; i++) {
           if (i == n) {
               strcpy(list[n], word);
               n++;
               break;
}
           k = strcmp(word, list[i]);
           if (k == 0) {
               count[i]++;
               break;
           }
           if (k < 0) {
               for (j = n; j > i; j--)
                   strcpy(list[j], list[j - 1]);
               strcpy(list[i], word);
               n++;
               break;
           }
       }
   }

   printf(" Word list: ");
   for (i = 0; i < n; i++)
       printf("%s (%d) ", list[i], count[i]);
   return EXIT_SUCCESS;
}
