Use std::istringstream for input, std::ostringstream for output,
std::stringstream for both. Once you have created a stringstream, you
can use istream/ostream read/write facilities on it.

#include <iostream>
#include <cstring>
#include <sstream>

main()
{
std::stringstream sstr;
sstr << "balaji";
std::cout << sstr.str() << '\n';
sstr.str(""); //clear in-memory data
char buf[100];
strcpy(buf,"asdkjabvdba");
std::stringstream sstr1(buf);
std::cout << sstr1.str() << '\n';
}

Thanks,
Balaji.
