copied!<p>Your question is a little lacking in detail, but I'm assuming that you want to save your class objects, which are in an array, to disk.</p> <p>If that understanding is correct, then the solution wouldn't seem to hard.</p> <p>I would recommend using boost::serialize for saving your classes to disk (<a href="http://www.boost.org/doc/libs/1_54_0/libs/serialization/doc/index.html" rel="nofollow">http://www.boost.org/doc/libs/1_54_0/libs/serialization/doc/index.html</a>)</p> <p>As for your iteration process, here is an example that might help:</p> <pre><code>#include <string> #include <vector> #include <boost/shared_ptr.hpp> #include <boost/scoped_array.hpp> class PrettyPetunia { public: PrettyPetunia(){;} ~PrettyPetunia(){;} private: std::string _myName; }; typedef boost::shared_ptr<PrettyPetunia> PrettyPetuniaPtr; typedef std::vector<PrettyPetuniaPtr> PrettyPetunias; typedef PrettyPetunias::iterator PrettyPetuniasItr; void SaveClassObjectOutToDisk(const char* fileName, PrettyPetuniaPtr classObjectToSave); void IterateArrayToSaveToDisk(PrettyPetunias& petunias) { unsigned int loopCounter = 0; for (PrettyPetuniasItr itr = petunias.begin(); itr != petunias.end(); ++itr ) { boost::scoped_array<char> fileName ( new char[1024] ); // 1024 or PATH_MAX, your choice sprintf(fileName.get(), "data%d02.txt", loopCounter); PrettyPetuniaPtr ptr = (*itr); SaveClassObjectOutToDisk(fileName.get(), (*itr) ); } } void SaveClassObjectOutToDisk(const char* fileName, PrettyPetuniaPtr classObjectToSave) { // ... } </code></pre>
