• '<cstring>' is provided only for backward compatibility with ANSI C and provides the global string functions such as 'strcpy', 'strcat', 'memcpy' etc.
• '<sstring>' is not a header I know....I assume you rather mean '<sstream>' which provides the stream classes for strings.
• '<string>' is the header file for the STL 'string' class...

A sample would be

#include <iostream>
#include <sstream>
#include <string>

int main()
{
  std::ostringstream oss;
  oss << 10;
  std::string str = oss.str();
  std::cout << str << std::endl;
  return 0;
}
