Read newline using stream C++

Question

How do I also read a new line using C++ >> operator?

ifstream input(\"doc.txt\".c_str());
vector contents;
while (input >> word) {
    conten

Try using getline (http://www.cplusplus.com/reference/istream/istream/getline/). getline will go through each line (until it sees the new line character) and returns 0 when it reaches end of file. So after each call to getline and printing it print the \n as well. Here is an example for your problem, randFile is a random file with text in it.

  1 #include 
  2 #include 
  3 int main(){
  4 
  5   std::ifstream myFile("randFile", std::ifstream::in);
  6   char s[BUFSIZ];
  7 
  8   while(myFile.getline(s, BUFSIZ)){
  9     std::cout << s << std::endl;
 10     std::cout << "\\n"<< std::endl;
 11   }
 12 
 13   return 0;
 14 }
