hi
I have 2 files, the first one has class name pDisk
the second one has a class caled pFileTable : public pDisk
Please tell me what is wrong with my code:
here is the two classes
from File name : pDiskFile.h
Code:#ifndef P_DISK_FILE_H #define P_DISK_FILE_H #include <sstream> #include <vector> #include <string> #include <strstream> #include <iostream> #include <cstdlib> //#include <stdlib> #include <iomanip> #include <cmath> #include <math.h> #include <time.h> #include "utilities.h" #include "fileTable.h" //fstream pDISK; class pDisk { public: int fDisk(int number_Of_Blocks, int block_Size, string p_Disk_Name); // initialize disk int fsCreate(string p_Disk_Name); // creats the disk after the initialization and formats disk file with filesystem int fsOpen(string p_Disk_Name); // reads file system into into memory for manipulation and whatever...! int synch(); // synch memory data to disk file int addBlock(string file_Name, string buffer); // add block to file with content of buffer int delBlock(string file_Name, int block_Number); // delete block if in file int firstBlock(string file_Name); // return first block in file int nextBlock(string file_Name, int block_Number);// get next block in file int getBlock(string file_Name, int block_Number, string &buffer); // get buffer from block if in file void printDISK();// print the information from the disk to the screen string getPhysicalBlock( string file_Name, int block_Number, string & buffer); // this will get the blockSize and store it into a buffer. /* dealing with files in the disk these was eliminated after the second phase as we made a lot of changes in the file table and we don't have the time to finish them to be done later... */ int findBlock(string file_Name, int block_Number); // Find the Block in the File_name from the Block_Number int addFile( string file_Name, string fileBuffer); // add the name of the file to thr root and the file buffer to the disk int delFile( string file_Name); // Dellet a file from the disk int filePos(string p_Disk_Name); //it takes the file name and return it position in the vROOT vector. private: int numberOfBlocks; // number of blocks in pdisk int blockSize; // number of bytes per block int fatSize; // FAT size in blocks string pDiskName; // name of pdisk for file system int totalBlocks; // will have the number of the total blocks string dataBLOCKS; // will have all the blocks buffer as one string vector <int> vFAT; // memory storage for FAT information //vector <Pair> vROOT; // memory storage for root information vector <int> vROOT; // memory storage for root information vector <string> vFileName;// the file Names in the root //vector <Pair> vBUFFER; // memory storage:Buffer of the disk, and the block number };// end of Class PDisk.
the second class is from file : fileTable.h
the error isCode:#ifndef __FILE_TABLE_H #define __FILE_TABLE_H #include <sstream> #include <vector> #include <string> #include <strstream> #include <iostream> #include <cstdlib> //#include <stdlib> #include <iomanip> #include <cmath> #include <math.h> #include <time.h> #include "pDiskFile.h" #include "utilities.h" string flat_File; int headerBlock; class FileTable: public pDisk // OOP //^^^^^^^^^^^line34^^^ { public: FileTable(); FileTable(string flat_File); int buildFile( string input_File); int addRecord( string record, string buffer); string searchBlock( string block, int key, string value); int searchAll( string value); int Search( string key, string value, int feild); int fieldQuery( string qur, int field); void display( string find, int flag); void Cat(); int lookUp(); string pack( vector<string> discr, vector<int> links); void unpack(string buffer, vector<string>& discR, vector<int> links); // from part III int buildRoot( vector<string> key, vector<int> blocks); // build the Tree root. int bTreeSearch( int node, string key);// Search the tree for a key. int addBTree( int node, string & key, int& block); // add a new key to the tree int EXTERInsert( int node, string key, int block, string & median, int & new_Block); int INTERinsert( int node, string key, int block, string & median, int & newBlock); int extDelete( int node, string key); int buildKeys( string input_File); // build the keys of the tree void metaFile( string block, int location);// the file void buildNewRoot( string median, int leftChild, int rightChild); int fixChild(int child, int sibling, string & median); private: pDisk pTableDISK; //************here is the problem**********// fstream fileName; };// Class FileTable
fileTable.h:34: syntax error before `;'
fileTable.h:37: parse error before `{'
fileTable.h:40: parse error before `)'
fileTable.h:69: parse error before `private'
fileTable.h:79: invalid use of undefined type `class FileTable'
fileTable.h:36: forward declaration of `class FileTable'
Please , I am about to give up:.... all the errors that I have in my code is "the second class can't make a variable from the first class. I don't know why....
Thanx a lot
