For this assignment you will be combining file IO, dynamic memory allocation, and structures
by processing a NFL team roster. Football I usually big among the population, so I picked a
football roster for the input file with standardized data. Additionally, football rosters are large
enough so your solution will be not trivial.
Part 1: Count the number of players
I have attached the 2015 Kansas City Chiefs in CSV format. Many datasets out there are in CSV
format. CSV stands for comma separated values. The basic format of each object of the dataset is
a line in the datafile, and each field of that element is separated by a comma, hence the name.
For this part, I want you to count the number of players on the roster.
You will use this number to dynamically allocate memory in the next part so it's important you
get the number correct.
As a test, there are 90 players on the roster, so if you get more or less than that don't move to part
2.
Part 2: Read the players into a data structure
Now that you know how many players there are on the roster, you will now need to read the
players from the roster into your array.
Before you do that you will need to create a data structure to hold the data.
Each player has specific attributes associated with them and each has a type that should be used
with that attribute. I suggest you use the following:
number: unsigned char (a char is just a byte of data and football numbers go from 1-99)
name: string (AKA char*)
pos: string
ht: string
wt: integer (some players weight more than 256)
age: unsigned char
exp: string
college: string
Make a struct using the above attributes.
Now you should allocate an array that can hold all this data for all the players. How will you do
that?
Then read in the players data, and store them in the array you just created.
Part 3: Query the Data
For this part, prompt the user for a player number, the after the number is entered ,search your
player array for that number, then print out all the associated player data based on that query. If
the there is no player associated with that return an error message. Your program should continue
letting the user query the data until the user types -1.
I did this one for my self. I did part one.
But I have no idea how to handle part 2 and 3
Here is my code.
Code:#include <stdio.h> #include <stdlib.h> int main() { FILE *fp; int count = 0; char c; fp = fopen("cheifs2015.csv","r"); for (c = getc(fp); c != EOF; c = getc(fp)) { if ( c == '\n') count = count + 1; } fclose(fp); printf("%d players\n", count); struct players { unsigned char number; char *name; char *pos; char *ht; int wt; unsigned char age; char *exp; char *college; }; struct players *x = malloc(sizeof(*x)); // allocated array return 0; }
I can't attach files so here is file information.
