c++ - reading a line from ifstream into a string variable -

in next code :

#include <iostream> #include <fstream> #include <string> using namespace std; int main() { string x = "this c++."; ofstream of("d:/tester.txt"); of << x; of.close(); ifstream read("d:/tester.txt"); read >> x; cout << x << endl ; } output :

this

since >> operator reads upto first whitespace output. how can extract line string ?

i know form of istream& getline (char* s, streamsize n ); but want store in string variable. how can ?

use std::getline() <string>.

istream & getline(istream & is,std::string& str)

so, case be:

std::getline(read,x);

c++ string ifstream getline
