用cpp读入：
代码

#include<iostream>
#include<fstream>
#include "opencv2/opencv.hpp"
using namespace std;
using namespace cv;

int main() {
	string path_to_read = "0.txt";
	fstream indata(path_to_read);
	string s;
	//while (indata >> s) {
	while(getline(indata,s)){
		cout << "this is s:" << s << endl;
	}
	//system(pause);
	//cvWaitKey();
	system("pause");
	return 0;
}

结果如下：
