Program stopping for no reason

I'm doing a program to alphabetize and show the last name of the alphabetical order, with the end of the EOF file, only it only works if I do not put names without space, if I put a name with space it simply to.

Example input:

Wow, how beautiful the sky is.

The sun

Output

The sun

My code

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
struct p
{
  char nome[100];
};

int ordena(const void *a, const void *b)
{
  int   r = strcasecmp((*(struct p*)a).nome, (*(struct p *)b).nome);
  if (r == 0)
  {
    return 0;
  }
  else if(r < 0)
  {
    return -1;
  }
  else
  {
    return 1;
  }
}

int main(int argc, char** argv)
{
  char teste[1000];
  int i = 0;
  struct p nomes[2000];
  while(scanf("%[^\n]", teste) != EOF)
  {
     strcpy(nomes[i].nome, teste);
     i++;
 }

   qsort(nomes, i, sizeof(struct p), ordena);
   int soma = i - 1;
   printf("%s\n", nomes[soma].nome);

  return 0;
}
