按特定顺序输出地图

Question

Hopefully I can explain exactly what's going on, but basically I have a map of words and their corresponding line numbers on a document that is read in by the program. I can output the map and everything with the words and their line numbers but I'm confused on how to change how they output. So here is the code:

here is the main:

#include <iostream>
#include <string>
#include <vector>
#include <set>
#include <algorithm>
#include <fstream>
#include "dictionary.h"
#include "document.h"

using namespace std;

void sentancetoword(string sentance, set<string> words, int lineNum)
{
    dictionary d;
    document doc;
    bool wordCheck;
    string word;
    stringstream ss(sentance);

    while (ss >> word)
    {
        wordCheck = d.findWord(word, words);
        if(!wordCheck)
        {
            doc.missingMap(word, lineNum);
        }
    }
    doc.displayMap();

}

string letterCheck(string sentance)
{
    for(unsigned i = 0; i < sentance.length(); i++)
        {
            if (!isalpha(sentance[i]))
            {
                sentance[i] = ' ';
            }
        }
    return sentance;
}

int main(int argc, char* argv[])
{
    dictionary dic;
    document doc;
    set<string> words;
    set<string>::iterator it;
    string doc_word;
    int lineNum = 1;
    ifstream in;
    in.open(argv[1]);
    string word;

    while (in >> word)
    {
        transform(word.begin(), word.end(), word.begin(), ::tolower);
        words.insert(word);
    }

    in.close();

    //dic.makeSet(words);

    ifstream in2;
    in2.open(argv[2]);
    while (getline(in2, doc_word))
    {
        transform(doc_word.begin(), doc_word.end(), doc_word.begin(), ::tolower);
        doc_word = letterCheck(doc_word);
        sentancetoword(doc_word, words, lineNum);
        lineNum++;

    }

    in2.close();

    system("pause");
    return 0;

}


#include "document.h"


document::document(void){}
document::~document(void){}

void document::missingMap(string word, int lineNum)
{
    misspelled[word].push_back(lineNum);        
}
void document::displayMap()
{
    for (map<string, vector<int>>::iterator i = misspelled.begin(); i != misspelled.end(); i++)
    {
        cout << i->first << ": ";
        for (vector<int>::iterator j = i->second.begin(); j != i->second.end(); j++)
        {
            cout << *j << endl;
        }
    }



}

so the last function is doing the outputting of the map and it outputs as follows:

debugging: 1
process: 2
removing: 2
programming: 3
process: 4
putting: 4

but i need it to output like this:

debugging: 1
process: 2 4
programming: 3
putting: 4
removing: 2

is there something I'm doing wrong in the code or do i need to add a sort function to sort it by the words? I'm honestly lost and don't know where to go from here to get it to output only the word one time followed by the line numbers it appears on. If anyone could help that would be great, and if any more information is needed I'll be happy to add it to the question! Thanks!

Answer 1

Your output doesn't make sense, though I think you will want to do this:

cout << i->first << ": ";
for (vector<int>::iterator j = i->second.begin(); j != i->second.end(); j++)
{
    cout << *j << " ";
}
cout << "\n"; //endl is okay, but I prefer only for I really do need to flush the stream
