[ravishankar_bs]

can you please suggest how I can read a line containing many strings,parse it and obtain an array of strings(word by word) and number of strings as return.
Thanks

[Philip Nicoletti]

One way would be to read line by line into string,
then use that string as input to a stringstream.
Read from the stringstream to get the fields on that line.

#include <iostream>
#include <sstream>
#include <fstream>
#include <string>
#include <vector>

using namespace std;

int main()
{
  ifstream in("test.txt");
  if (!in)
  {
     cout << "problem with file open" << endl;
     return 0;
  }

  string line;
  string field;

  while (std::getline(in,line))
  {
      vector<string> vS;    // the array of words on the current line

      istringstream iss(line);
      while (iss >> field)
      {
          vS.push_back(field);
      }
      cout << "Number of fields in the line = " << vS.size() << endl;
  }


  return 0;
}
