C++연습_숫자 영어로 입력하면 숫자로 출력하기

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

map<string, int> reference;

string ones[] = { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten" };

void storeOnes() {
	for (int i = 0; i < 11; i++) {
		reference[ones[i]] = i;
	}
}

int main() {
	//set up
	storeOnes();
	string test;
	cout << "영어로 숫자를 써 주세요(붙여서입력해야 합니다. zero,one, two, three, four, five, six, seven, eight, nine, ten)\n  -> 입력해 주세요:  ";
	cin >> test;
	string buffer;


	for (int i = 0; i < test.length(); i++) {
		buffer.push_back(test.at(i));
		map<string, int>::iterator it = reference.find(buffer);
		if (it != reference.end()) {
			cout << (*it).second;
			buffer = "";
		}
	}
	cout << endl << endl;
	system("pause");
	return 0;
}
