[計程] resize的問題
後來發現老師的程式錯了一個不等號（只錯這邊）
助教叫我po出來的

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
using namespace std;
void get_names(vector <string> &);
void print_summary(const vector <string> &, const vector <int>);
void initialize(vector <int> &);
void tally(vector <int> &);
int main()
{ vector <string> cand_names(5);
vector <int> vote_counts(5);
get_names (cand_names);
vote_counts.resize(cand_names.size());
initialize(vote_counts);
tally(vote_counts);
print_summary(cand_names, vote_counts);
int bb; //這三行是因為我電腦有問題才加的 不用管
cout << "Program End. (Y)";
cin >> bb;
return 0;
}
void get_names(vector <string> & names)
{ ifstream names_in;
int cand=1;
names_in.open("name.txt");
names.resize(5);
while(names_in >> ws && !names_in.eof())
{ if(cand >= names.size())
//假如有4位候選人則name.size()=5
//所以應該要有等號
names.resize(names.size()+1);
names_in >> names[cand];
cand++;
}
names_in.close();
}
void print_summary(const vector <string> & names, const vector <int> counts)
{ int cand;
for (cand =1; cand<=counts.size(); cand++)
cout << names[cand] << ": " << counts[cand] << endl;
}
void initialize(vector <int> & counts)
{ int cand;
for (cand =1; cand<=counts.size(); cand++)
counts[cand]=0;
}
void tally(vector <int> & counts)
{ int cand;
ifstream vote_in;
vote_in.open("votes.txt");
while(vote_in >> ws && !vote_in.eof())

else cout << "Invalid vote:" << cand << endl;
}
vote_in.close();
}
