when i check50 my code I get this message :
:( print_winner identifies Bob as winner of election
print_winner function did not print winner of election
:( print_winner identifies Charlie as winner of election
print_winner function did not print winner of election
i tried the test 3 candidates a,b,c 4 voters who vote: a,b,b,c. The result i got is a c so there is something wrong but I can't see where.
I don't understand why it is not properly sorted in this case while in many other case my bubble sort is working.
Could you please explain or give a hint ? Many thanks
Here is my code
#include <stdio.h>
#include <string.h>
// Max number of candidates
#define MAX 9
// Candidates have name and vote count
typedef struct
{
string name;
int votes;
}
candidate;
// Array of candidates
candidate candidates[MAX];
// Number of candidates
int candidate_count;
// Function prototypes
bool vote(string name);
void print_winner(void);
int main(int argc, string argv[])
{
// Check for invalid usage
if (argc < 2)
{
printf("Usage: plurality [candidate ...]\n");
return 1;
}
// Populate array of candidates
candidate_count = argc - 1;
if (candidate_count > MAX)
{
printf("Maximum number of candidates is %i\n", MAX);
return 2;
}
for (int i = 0; i < candidate_count; i++)
{
candidates[i].name = argv[i + 1];
candidates[i].votes = 0;
}
int voter_count = get_int("Number of voters: ");
// Loop over all voters
for (int i = 0; i < voter_count; i++)
{
string name = get_string("Vote: ");
// Check for invalid vote
if (!vote(name))
{
printf("Invalid vote.\n");
}
}
// Display winner of election
print_winner();
}
// Update vote totals given a new vote
bool vote(string name)
{
for (int i = 0 ; i < candidate_count ; i++)
if (strcmp(name, candidates[i].name) == 0)
{
candidates[i].votes++;
return true;
}
return false;
}
// Print the winner (or winners) of the election
void print_winner(void)
{
for (int i = 0 ; i < candidate_count - 1 ; i++)
{
for (int c = 0 ; c < i - candidate_count - 1 ; c++)
{
if (candidates[c].votes < candidates[c + 1].votes)
{
int swap = candidates[c].votes;
candidates[c].votes = candidates[c + 1].votes;
candidates[c + 1].votes = swap;
}
}
}
printf("%s\n", candidates[0].name);
for (int i = 0 ; i < candidate_count - 1 ; i++)
{
if ((candidates[i + 1].votes) == (candidates[0].votes))
{
printf("%s\n", candidates[i + 1].name);
}
}
