replacing double space to single space

Question

How can I replace the double space into single space using C++

ex:

\"1  2  3  4  5\" => \"1 2 3 4 5\"

this is what I`ve done till no

Answer 1

In while loop of splitLines code, use this code.

  while((loc = line.find("  ")) != std::string::npos) //Two spaces here
  {
       line.replace(loc,2," "); //Single space in quotes
  }
  cout << line << endl;

Thats it. I haven't tried it out, let me know if it works.

And as fred pointed out, use pass by reference in splitLines function. The above solution is sub-normal and is O(n^2) complexity. This one is better.

  int loc = -1;
  while((loc = line.find("  ",loc+1)) != std::string::npos) //Two spaces here
  {
       line.replace(loc,2," "); //Single space in quotes
  }
  cout << line << endl;
