Homework SourseUsing C write a program using structs and the string class
Using C++ , write a program using structs and the string class.
Read a file containing team names, their conferences and divisions. This data will be stored in an array of structs.
Read a file containing scores. Each record in the file must be parsed to determine the winning and losing team. The number of wins, losses and percentage must be calculated using the data in the scores file.
The array of structs must be sorted by conference, division, and percentage to produce output equivalent to that shown below.
Use the input files, team name file (http://voyager.deanza.edu/~bentley/nfl_teams.txt)
and scores file (http://voyager.deanza.edu/~bentley/nfl_scores.txt).
The scores file may be updated again at a later date.
Use this struct to store the data for each team:
struct NFL_Team
{
string name;
string conference;
string division;
unsigned short wins;
unsigned short losses;
unsigned short ties;
float pct;
};
Use strings to store all character data for this assignment..
The program output must show the current standings using the team input data and the percentage calculations.
You may not use stringstream (or istringstream or ostringstream) objects or c-string function for this assignment.
Program Output
Output should look quite similar to the following. Note: the actual statistics will be different with the current score live
There are 32 NFL teams, 16 in each conference. The conferences are American and National. There are 8 divisions with 4 teams in each division.
The scores file will also require specific parsing techniques. Skip over the date column. To parse a scores record, use string functions looking for a comma. It will be handy to write a function that can pick out a team name from a text String. The string find() and rfind() functions will be useful here.
To calculate the team percentage, use the formula:
pct = (wins + 0.5 * ties) / total games played
To sort the data for the output standings, you might want to create a \"sortkey\" function, consisting of the conference, division, and percentage. Then you can sort using the \"sortkey\".
And finally, as usual, this assignment contains some subtle aspects. Be sure to start early and allow enough time to ask the instructor for help.
Recommendation, when you start, use a small subset of the scores file to make sure you are correctly calculating the statistics.
Be sure your code handles ties. There may be one/some in the test file used to grade your assignment.
