Functions
int	compute_bmi (int height, int weight)
	Compute the body-mass index (BMI). The height is in centimeters, so the computed value is off by 10,000. Integer division truncates, but we want to round off to nearest, so add 0.5 and then truncate by casting to an integer.
void	skip_line ()
	Skip the rest of the input line.
bool	get_record (std::vector< std::string > &names, std::vector< int > &heights, std::vector< int > &weights, std::vector< char > &sexes)
	Get a single person's record. Store the name, height, weight, and sex in the supplied vectors.
void	print_table (char sex, std::vector< int > const &heights, std::vector< int > const &weights, std::vector< int > const &bmis, std::vector< char > const &sexes, std::vector< std::string > const &names, int threshold)
	Print a table. Print a table of height, weight, sex, BMI, and name. Print only records for which sex matches sex. At the end of each table, print the mean and median BMI.
int	main ()
	Main program to compute BMI.

int compute_bmi	(	int	height,
		int	weight
	)

Compute the body-mass index (BMI). The height is in centimeters, so the computed value is off by 10,000. Integer division truncates, but we want to round off to nearest, so add 0.5 and then truncate by casting to an integer.

Parameters:

	height	The person's height in centimeters.
	weight	The person's weight in kilograms.

Returns:

the person's BMI, rounded to an integer

bool get_record	(	std::vector< std::string > &	names,
		std::vector< int > &	heights,
		std::vector< int > &	weights,
		std::vector< char > &	sexes
	)

Get a single person's record. Store the name, height, weight, and sex in the supplied vectors.

Parameters:

	names	array of persons' full names
	heights	array of height in centimeters
	weights	array of weight in kilograms
	sexes	array of persons' sex: 'M' means male and 'F' means female

Returns:

true to continue reading records or false to stop

void print_table	(	char	sex,

		std::vector< int > const &	weights,
		std::vector< int > const &	bmis,
		std::vector< char > const &	sexes,
		std::vector< std::string > const &	names,
		int	threshold
	)

Print a table. Print a table of height, weight, sex, BMI, and name. Print only records for which sex matches sex. At the end of each table, print the mean and median BMI.

Parameters:

	sex	the sex to match
	heights	the array of heights
	weights	the array of weights
	bmis	the array of BMIs
	sexes	the array of sexes
	names	the array of names
	threshold	print only elements for which BMI > this
