标准C++中怎样读取整个文本文件到string中

Answer 1

#include <iostream>
#include <string>
#include <fstream>

using namespace std;

int main() {
ifstream fin;
string temp[20],total = "";
char filename[60];
int i = 0;
cout << " Enter the reference file: \n";
cin.getline(filename,'\n');
fin.open(filename,ios::in);
while(fin.good() && i < 20){
getline(fin,temp[i]);
total += temp[i]; // += 已被重载
cout << temp[i] << endl;
i++;
}
//
return 0;
}
