Command Line Argument: When starting the program, the user will provide one command line argument. The command line argument will be the name of the file that contains the information about schools and football matches. Your program will open the specified file and parse the contents. If the user does not provide the name of an existing file the program should print out an error message and quit. Sorting and Printing: Once the program begins, the user should be prompted with a list of different ways to utilize the historical information. Available Options: Display each school's earliest year on file: print each school's name, along with the year of its first recorded football game. Each entry must also display the city where the school is located and the school's moniker. The ordering of these entries is up to you. ● • Best year (by points): You must process all of the Match entries and compute the total number of points that were scored (by the home team) during each year. You will then determine which year was the "best" year for the school, based on the highest number of points scored. After calculating the sum you will print the following information for each school (sorted in alphabetical order by name of school): • The name of the school • The year that had the most points scored by the home team • The total number of points that the home team scored in that particular year • Extra credit (5 pts): Also display a list of all the opponent teams that the school beat during their best year. • Sort schools by overall historical performance: If the user picks this option the schools must be displayed in descending order by their historical winning ratios (i.e. sorted by winRatio). (You also need to print the name of the school.) • Quit: The program will exit.
Your program should continue sorting and printing/writing until the user chooses to quit. For the sorting functionality, you can write your own sorting function, or consider using C++'s built in sort function. Required Structs: The following structs are required in your program. They will help organize the information that will be read in (or derived) from the files. You cannot modify, add, or take away any part of the struct. The School struct will be used to hold information about each school. Note that the struct contains a member variable named "winRatio". That particular value is derived from the total number of wins, losses, and ties in the school's history. From a mathematical perspective: winRatio = (total # of wins) / ((total # of wins) + (total # of losses) + (total # of ties))
The School struct is defined as follows: struct School { string name; string moniker; string city; double winRatio; int numMatches; // added on June 28th struct Match* array; }; The Match struct will hold information about the individual football matches. struct Match { }; unsigned int year; unsigned int homeScore; string opponentName; unsigned int opponentScore; Required Functions: You must implement the following functions in your program. You are not allowed to modify these required function declarations in any way. Note #1: it is acceptable if you choose to add additional functions (but you must still include the required functions). Note #2: You must write the dynamic memory allocation functionality yourself (i.e. no using vectors). This function will dynamically allocate an array of schools (of the requested size): School* create_school_array(int); This function will fill a School struct with information that is read in from the text file. Hint: "ifstream &" is a reference to a filestream object. You will need to create one and pass it into this function to read from the input text file.
void load_school_data(School*, int, ifstream &); This function will dynamically allocate an array of matches (of the requested size): Match* create_match_array(int); This function will fill a Match struct with information that is read in from the text file. void load_match_data(Match*, int, ifstream &); You need to implement a function that will delete all the memory that was dynamically allocated. You can choose the prototype. A possible example prototype includes the following: void delete_school_data(School*, int);
Required Input File Format Your program must accommodate the file format as specified in this section. The file content will be provided in sets (corresponding to each school). Furthermore, each school will be accompanied by a listing of the historical football matches. Each input file will follow the format shown below. A sample file is available for download here. Important observation: a semicolon is used to separate the individual fields on each line. <total number of schools in file (integer) > <name of first school>; <moniker>; <city>; <number of matches in school history> <year>; <home score>; <opponent name>; <opponent score> <year>; <home score>; <opponent name>; <opponent score> <year>; <home score>; <opponent name>; <opponent score> <name of first school>; <moniker>; <city>; <number of matches in school history> <year>; <home score>; <opponent name>; <opponent score> <year>; <home score>; <opponent name>; <opponent score> <year>; <home score>; <opponent name>; <opponent score> <year>; <home score>; <opponent name>; <opponent score> <year>; <home score>; <opponent name>; <opponent score> <name of third school>; <moniker>;<city>; <number of matches in school history> <year>; <home score>; <opponent name>; <opponent score> <year>; <home score>; <opponent name>; <opponent score> ...
Example Operation The following snippet of text shows an example implementation of the athletic record program. Note that this example does not illustrate all required behavior. You must read this entire document to ensure that you meet all of the program requirements. Note: the filename is provided as a command line argument. It's not hard-coded (the TA could provide any valid filename while testing your code). $ ./assign1 sample_1.txt Which option would you like to choose?
