testwordcount.cpp

一个很好的计算文字数目的例子,现在一个缺点就是计算中文的时候可能不是很准确

#include <iostream>
#include <string>
#include <vector>
#include <fstream>
#include "wordcount.h"


using namespace std;//::cout;

    for(vec_sz i = 0; i < size; ++i)
	{
		if(word == output_words[i]) 
			return true;
	}
    return false;
}

void main()
