struct congnhan {
  char hoten[35];
  } danhsach[MAX];
int n = 0;

  char hoten[35], tmp[3];
  int i;
  do {
    printf("\nNhap ho ten CN : ");
    gets(hoten);
    if (strlen(hoten))
    {
      strcpy(danhsach[n].hoten,hoten);
      gets(tmp);
      n++;
    }
  } while (strlen(hoten));
}

void timkiem()
{
  char hoten[5];
  int i = 0, found = 0;
  printf("\nCho ho ten CN can tim : ");
  gets(hoten);
  if (strlen(hoten))
    while (i<n)
      if (strcmp(danhsach[i].hoten,hoten) == 0)
      {
         printf("\nHo va ten : %s", danhsach[i].hoten);
         found = 1;

      traloi = getch();
    } while (traloi < '1' || traloi > '2');
    putc(traloi, stdout);
    switch (traloi)
    {
       case '1' : nhapmoi();
                  break;
