My solution for UVA 10226

uva_10226.cpp

#include <iostream>
#include <iomanip>
#include <string>
#include <map>
using namespace std;

map<string, int> m;
int n;
double trees;
string s;
int main() {
    ios_base::sync_with_stdio(false);
    cin.tie(NULL);

    cin >> n; getline(cin, s); getline(cin, s);
    cout << setprecision(4) << fixed;
    for(int i=0; i<n; i++) {
	if(i > 0) cout << '\n';
	trees = 0;
	m.clear();
	while(getline(cin, s) && s!="") {
	    m[s]++;
	    trees++;
	}
	for(map<string, int>::iterator it=m.begin(); it!=m.end(); it++) 
	    cout << it->first << " " << (it->second)*100/trees << '\n';
    }

    return 0;
}
