#include <map>
#include <fstream>
#include <iostream>
#include <string>

using namespace std;

void display_map(map<string, int> &wmap);

int main()
{
const char *szInputFileName="Text.txt";
ifstream ifs(szInputFileName);
string szTemp;
map<string, int> wmap;

while (ifs>>szTemp)
wmap[szTemp]++;

display_map(wmap);

return false;
}

void display_map(map<string, int> &wmap)
{
map<string, int>::const_iterator map_it;
for (map_it=wmap.begin(); map_it!=wmap.end();map_it++)
{
cout<<"(/""<<map_it->first<<"/","<<map_it->second<<")"<<endl;
}
}
