Question

Needs to be coded in c, main needs to take command line arguments, thus: int main(int argc, char*argv[])

it will take three files, htls.dat, roms.dat, cst.dat

htls.dat

4
Hilton
BstWestern
HolmesEstates
MoriarityInn

roms.dat

5
Standard
Queen
King
Suite
Presidential

cst.dat

50 75 120 145 200
75 125 155 200 355
145 175 250 350 400
300 400 500 600 900

needs to have following functions:

const char *const GetHotelName(int hotel) - returns string from hotelnames global variable

const char*const GetRoomName(int room) - returns string from roomnames global variable

void PrintHotelOptions() - prints list of hotels

void PrintRoomOptions() - prints list of rooms

void PrintHotelRoomsLessThan(int iLimit) - prints hotels and prices

int getMainMenuChoice() - Displays menu and returns user's selection

int GetRoomPrice(int hotel, int room) - returns price of a fiven room in a given hotel

void printHotelsByRoom(int room) - prints list of hotels and prices for given room type

int LoadHtelNames(char *sFileName) - loads hotel name from .dat into memory

int LoadRomNames(char *sFileName) - loads room name from .dat into memory

int LoadCstMatrix(char *sFileName) - loads cost matrix from .dat into memory

void PrintCostMatrix() - prints out cost matrix to screen

void PrintHotelNames() - prints hotel name list to screen

void printRoomNames() - prints room type list to screen

OUTPUT:

Hotel Names:

Hilton

BstWestern

HolmesEstates

MoriarityInn

Room Names:

Standard

Queen

King

Suite

Penthouse

CostMatrix:

Hilton, Standard = 50

Hilton, Queen = 75

Hilton, King = 120

Hilton, Suite = 145

Hilton, Penthouse = 200

BstWestern, Standard = 75

BstWestern, Queen = 125

BstWestern, King = 155

BstWestern, Suite = 200

BstWestern, Penthouse = 355

HolmesEstates, Standard = 145

HolmesEstates, Queen = 175

HolmesEstates, King = 250

HolmesEstates, Suite = 350

HolmesEstates, Penthouse = 400

MoriarityInn, Standard = 300

MoriarityInn, Queen = 400

MoriarityInn, King = 500

MoriarityInn, Suite = 600

MoriarityInn, Penthouse = 900
