1. 读文件流
string readpro(const char* path) {
ifstream infile(path);
char buf[1024];
string message = "";
// 假如 infile 后面没有路径,要先打开文件 infile.open(path);
if (infile.is_open()) {
while (infile.good() && !infile.eof()) {
memset(buf, 0, 1024);
infile.getline(buf, 1024);
message += buf;
}
infile.close();
} else
cout << "error!" << endl;
return message;
}
2. 写文件流:
ofstream outfile("/data/name.out", ios::trunc);
outfile.write((char*)result.string(), result.length());
outfile.close();
