Question

1. Where do I save the ACCOUNT1 & 2? 2. Or do I link them using Dev C++, if yes how? 3. I have compiles but I have one error but no program is excuting. 4. I know the files need to be opened but how? I am using Text Book " Extended Prelude to Programming and the examples or horible. Is there a better book for Pramming and Algorithms & Design? // The two data files being read are: ACCOUNT1 and ACCOUNT2 // The output data file being written is: ACCOUNT3 // // Each record in the files is as follows: // AcctNo Name Balance // (Int) (String) (Double) #include // Standard Library - used by system("PAUSE"); #include // I/O stream - used by cin and cout #include // I/O manipulation - used for formatting #include // File stream - used by file input and output routines using namespace std; // used by iostream and fstream // Create a data structure that identifies how a bank record will look typedef struct { int AcctNo; char Customer[40]; double Balance; } BankRecord; /////////////////////////////////////////////////////////////////////// ///////////////// Here is the program ///////////////////////////////// /////////////////////////////////////////////////////////////////////// int main(int argc, char* argv[]) { // // create variables of type BankRecord for use within the program // BankRecord DataFromFile1; BankRecord DataFromFile2; char buff[80]; // // create links from the disk into our program and // make sure that the program can open the files // ifstream file1("ACCOUNT1"); // ifstream opens the file for input if (!file1) { cout << "Unable to open ACCOUNT1 for input" << endl; return 1; // return non-zero indicates an error } ifstream file2("ACCOUNT2"); // ifstream opens the file for input if (!file2) { cout << "Unable to open ACCOUNT2 for input" << endl; return 2; // return non-zero indicates an error } ofstream file3("ACCOUNT3"); // ofstream opens the file for output if (!file3) { cout << "Unable to open ACCOUNT3 for ouptut" << endl; return 2; // return non-zero indicates an error } // // Read the first record of each file // file1 >> DataFromFile1.AcctNo >> DataFromFile1.Customer >> DataFromFile1.Balance; file2 >> DataFromFile2.AcctNo >> DataFromFile2.Customer >> DataFromFile2.Balance; // // While not end-of-file on both files, read a record from each file and write // it to the output file. This code needs to be changed to correctly merge // the files so that the output file is ordered by account number in // increasing order.
