tell cin to stop reading at newline

Question

Suppose I want to read line a of integers from input like this:

1 2 3 4 5\n 

I want cin to stop at '\n' character but cin doesn't seem to recognize it.

Below is what I used.

vector<int> getclause() {   char c;   vector<int> cl;    while ( cin >> c && c!='\n') {         cl.push_back(c);     cin>>c;   }   return cl; } 

How should I modify this so that cin stop when it see the '\n' character?

Answer 1

Use getline and istringstream:

#include <sstream> /*....*/ vector<int> getclause() {   char c;   vector<int> cl;   std::string line;   std::getline(cin, line);   std::istringstream iss(line);   while ( iss >> c) {         cl.push_back(c);   }   return cl; } 

Answer 2

You can use the getline method to first get the line, then use istringstream to get formatted input from the line.
