File operations using objects in C++ - GetDetails method in the data access class

Category: Programming Tutorials Date: Tuesday, July 19, 2016

For the C++ training group, from our classroom discussions on 19th July, 2016

This is the code which you should practice in the GetDetails method in the BranchDA data access class.

static Branch* GetDetails(int branchId)
    {
        bool recordFound = false;

        Branch *branch = new Branch();

        // Add the branch information to the file

        // Create object of the file handling class
        fstream fs;

        // Create the connection
        // Open the connection

        fs.open ("BranchData.dat", ios::in | ios::out | ios::binary);

        // Read or write the data

        fs.seekp(0, ios::beg);
        while(fs.read((char*)branch, sizeof(Branch)))
        {
             if(branch->GetId() == branchId)
             {
                 recordFound = true;
                 break;
             }
        }

        fs.close();

        if(recordFound == false)
            return NULL;
        else
            return branch;
    }
