} PersonData;
PersonData candidate[MaxCandidates];
typedef struct {
int valid, spoilt;
} VoteCount;
int main() {
void initialize(PersonData[], int, FILE *);
VoteCount processVotes(PersonData[], int, FILE *, FILE *);
void printResults(PersonData[], int, VoteCount, FILE *);
PersonData candidate[MaxCandidates+1];
VoteCount count;
FILE *in = fopen("votes.txt", "r");
FILE *out = fopen("results.txt", "w");
initialize(candidate, MaxCandidates, in);
count = processVotes(candidate, MaxCandidates, in, out);
printResults(candidate, MaxCandidates, count, out);
fclose(in);
fclose(out);
} //end main
The declarations of PersonData and VoteCount come before main. This is done so that other
functions can refer to them, without having to repeat the entire declarations. If they were declared
in main, then the names PersonData and VoteCount would be known only in main, and other
functions would have no access to them.
Now that we know how to read and process the votes, it remains only to determine the
winner(s) and print the results. We will delegate this task to the function printResults.
Using the sample data, the array candidate will contain the values shown below after all the
votes have been tallied (remember, we are not using candidate[0]).
