I did it. Now how to see which element repeats the most and how many times?

string str[8] = {"zxc", "zxc", "asd", "qwe", "zxc", "asd", "qwe", "jkl"};
vector<string> v_strAll;
vector<string> v_strUnique;
list<pair<string,size_t>> counts;

v_strAll.assign(str,str+_countof(str));
sort(v_strAll.begin(),v_strAll.end());
unique_copy(v_strAll.begin(),v_strAll.end(),back_inserter(v_strUnique));

std::vector<string>::iterator it = v_strUnique.begin();
while(it != v_strUnique.end())
{
	counts.push_back(make_pair(*it,count_if(v_strAll.begin(),v_strAll.end(),[it](const std::string& s1){return s1 == *it;})));
	++it;
}

for_each(v_strUnique.begin(),v_strUnique.end(),[&counts,v_strAll](const std::string& str){counts.push_back(make_pair(str,count_if(v_strAll.begin(),v_strAll.end(),[str](const std::string& s1){return s1 == str;})));});

ifstream file("file.dat");

vector<string> lines;
string line;

while (getline(file, line))
    lines.push_back(line);
