Question

What's went wrong??

Here is the program what count most repeated word in a file. I has problem in my output : the code count word containing number or spaces .

#include <iostream>
#include <fstream>
#include <map>
#include <algorithm>
#include <vector>
#include <sstream>
#include <algorithm>
#include <cctype>

using namespace std;

//function to sort the words based on their occurences
bool sortByVal(const pair<string, int> &word1,
const pair<string, int> &word2)
{
return (word1.second > word2.second);
}

int main()
{

//name of file
string filename;

//input the name of file
cout << "Enter the name of the text file: ";
cin >> filename;

//open the filestream
ifstream infile("hitchhikersguide.txt", ios::in);

//if file opening fails
if (infile.fail())
{
cout << "Error, The file isn't opening" << endl;
exit(1);
}

//map to store word and its frequency
map<string, int> frequencyMap;

//read words from file and store it in map
string word;
while (!infile.eof())
{
infile >> word;

//transform word to all uppercase
transform(word.begin(), word.end(), word.begin(), ::toupper);

//remove punctuations
for (int i = 0, len = word.size(); i < len; i++)
{
if (ispunct(word[i]))
{
word.erase(i--, 1);
len = word.size();
}
}
remove(word.begin(), word.end(), ' ');

//insert in map
if (frequencyMap.find(word) != frequencyMap.end())
{
frequencyMap[word]++;
}
else
{
frequencyMap[word] = 1;
}
}

//vector to sort words based on their frequncies
vector<pair<string, int>> vec;

for (auto it = frequencyMap.begin(); it != frequencyMap.end(); it++)
{
vec.push_back(make_pair(it->first, it->second));
}

//sort the vector
sort(vec.begin(), vec.end(), sortByVal);

//output 10 words
for (int i = 0; i <= 30; i++)
{
cout << vec[i].first << ": " << vec[i].second << endl;
}

infile.close();
}
