Thread: file and string streams usage

Is it possible to read from a file into an istringstream.

I did this little program to write to a sequential file, but was wondering about random access files.

Code:

#include <iostream>
using std::cout;
using std::endl;
using std::cerr;
using std::ios;

#include <stdlib.h>
#include <string>
using std::string;

#include <sstream>
using std::ostringstream;

#include <fstream>
using std::ofstream;

#include <cstdlib> // exit prototype

int main(int argc, char *argv[])
{
  ostringstream record;
  ofstream outClientFile("clients.txt",ios::out);
  
  //exit program if unable to create file
  if (!outClientFile){
    cerr << "File could not be opened"<<endl;
    exit(1);
  }
  
      
    string first_name("John");
    string last_name("Doe");
    
    int heightcm=175;
    double weightkg=200;
    
    record << first_name<<" "<<last_name<<" "<<heightcm<<" "<<weightkg;
    outClientFile<<record.str();
    cout << record.str();
        
      
  system("PAUSE");	
  return 0;
}
