如下所示:
#include <string> #include <fstream> #include <sstream> #include <iostream> #include <stdlib.h> using namespace std; //从文件读入到string里 string readFileIntoString(char * filename) { ifstream ifile(filename); //将文件读入到ostringstream对象buf中 ostringstream buf; char ch; while(buf&&ifile.get(ch)) buf.put(ch); //返回与流对象buf关联的字符串 return buf.str(); } int main() { //文件名 char * fn="a.txt"; string str; str=readFileIntoString(fn); cout<<str<<endl; system("pause"); }
