C++ PROGRAM QUESTION!
Module 10
Question 1
Complete the prog38.cpp to display random records from the random file.
I need to do only this part!: //TODO : Ask three options as first record, last record or the record number
PROG38.cc
#include
#include
#include
#include
#include "ClientData.h" // ClientData class definition
#include "ClientData.cpp"
using namespace std;
void outputLine( ostream&, const ClientData & ); // prototype
int main()
{
ifstream inCredit( "credit.dat", ios::in | ios::binary );
// exit program if ifstream cannot open file
if ( !inCredit )
{
cerr << "File could not be opened." << endl;
exit( EXIT_FAILURE );
} // end if
// output column heads
ClientData client; // create record
int r;
cout << "Enter record to read ";
cin >> r;
//TODO : Ask three options as first record, last record or the record number
//FILL CODE
// Read the record based on the user value
inCredit.seekg (sizeof(ClientData)*(r-1), ios::cur);
// read first record from file
inCredit.read( reinterpret_cast< char * >( &client ),
sizeof( ClientData ) );
cout << left << setw( 10 ) << "Account" << setw( 16 )
<< "Last Name" << setw( 11 ) << "First Name" << left
<< setw( 10 ) << right << "Balance" << endl;
outputLine( cout, client );
}
void outputLine( ostream &output, const ClientData &record )
{
output << left << setw( 10 ) << record.getAccountNumber()
<< setw( 16 ) << record.getLastName()
<< setw( 11 ) << record.getFirstName()
<< setw( 10 ) << setprecision( 2 ) << right << fixed
<< showpoint << record.getBalance() << endl;
} // end function outputLine
