How to print string in one line separated by space using stringstream

Question

0.00/5 (No votes)

See more:

string s:
stringstream ss << "Invalid Input";
While(!(ss).fail())
{ ss >> s;
cout << s;
}

Outputs:
Invalid
Input

But I want output:
Invalid Input (in single line separated by space)

What I have tried:

setw(1)
stringstream ss << noskipws << "Invalid Input ";

Solution 1

If you need a line the use getline:

C++

 #include <string>
 #include <iostream>
 #include <sstream>
 using namespace std;

int main()
{
  string s;
  stringstream ss;
  ss << "Invalid Input";

  while (ss.good())
  {
    string line;
    getline(ss, line);
    cout << line;
  }
}
