You will write a program that reads a binary file that contains records of creatures. Each record can be stored in a Creature struct. You should present the user with a menu of three options: display a specific creature, display all the creatures sorted by name, or quit. If the user chooses to display a specific creature, you should ask the user which creature to display

getCreatureNumber gets and returns the record number from the file that the user would like to be displayed

PARAM: numCreatures should be the value of the total number of records (creatures) in the file

PRE: numCreatures contains a value that is equal to the number of records in the file

POST: A value between 1 and numCreatures is returned as selected by the user

NOTE: Do not allow a value less than 1 or greater than numCreatures to be returned

/

int getCreatureNumber(int numCreatures)

{

}

/

displayCreature displays record number num from file

PARAM: file is a fstream that should be open for input and binary

num contains the record number that is to be read in file

PRE: file is a fstream that is open for input and binary

num is a value between 1 and the number of records in file

POST: The record number num is displayed to the monitor

/

void displayCreature(fstream& file, int num)

{

}

/

displaySorted should read file into a vector. It should then sort the vector by

the name of the creature. Last it should display the vector

PARAM: file is a fstream that should be open for input and binary

PRE: file is open for input and binary

POST: Each record is displayed sorted by the name of the creature

/

void displaySorted(fstream& file)

{

}
