  printf("Size of char: %ld\n", sizeof(char));
  printf("Size of short: %ld\n", sizeof(short int));
  printf("Size of int: %ld\n", sizeof(int));
  printf("Size of long: %ld\n", sizeof(long int));
  printf("Size of float: %ld\n", sizeof(float));
  printf("Size of double: %ld\n", sizeof(double));
  printf("Size of void: %ld\n", sizeof(void));
  return 0;
}
