How to read from file in c++

hitokiri_maniac — Wed, 10 Sep 2008 16:19:03 +0800

Hi i can't figure how to read from my save file and put the input that read from my save file instead of keying input in my program

my save file function

CODE

void save(string filename)
{

ofstream fout(filename.c_str());
if (fout.is_open())
{
if ( listIsEmpty() ) {
cout << "List is empty, nothing to save." << endl;
system("PAUSE");
} else {
currentPtr = listHead;
while (currentPtr != NULL)
{
fout << currentPtr->b.destination;
fout << currentPtr->b.username;

currentPtr = currentPtr->next;
}
}
cout <<"Record is saved" <<endl;
} else
{
cerr << "Can't open file " << filename << endl;
system("PAUSE");
}
fout.close();
}

my add function

CODE

void addBooking()
{
char destinationString[15],usernameString[30],continueAdding='Y';

system("CLS");
cout << "Add new Booking";
cout << "\n-------------";

do
{
while (!cin.get()) {};

cout << "**************************" << endl;
cout << "** View Flight Schedule **" << endl;
cout << "****************************************************************************************************************************************************************"<<endl;
cout << " Flight Code"<< setw(7) << "From" << setw(14) << "Destination" << setw(10) << "Date" << setw(10)<< "Time" << setw(10) << "Price" << setw(14) << "Seat Left " <<endl;
for (int i = 0; i < i_schedule; i++)
{
cout << " " << sche[i].flightcode << setw(12) <<sche[i].from << setw(10)<<sche[i].destination<< setw(14)<<sche[i].date<<setw(10)<<sche[i].time<<setw(10)<<sche[i].price << setw(10)<<sche[i].seatleft<< endl;
}
cout << "****************************************************************************************************************************************************************"<<endl;
system("pause");
cout << "Enter your Destination :";
cin.getline(destinationString,30);
strupr(destinationString);

cout << "Enter Customer Name :";
cin.getline(usernameString,30);
strupr(usernameString);

Booking addBooking(destinationString,usernameString);

createNode(addBooking);

cout << "\nDo you want to add another booking? [Y/N] :";
cin >>continueAdding;
continueAdding = toupper(continueAdding);

}while (continueAdding!='N');
}

Deprecated API and Unchecked operation

hitokiri_maniac — Fri, 21 Dec 2007 14:40:37 +0800

hi.. hope anyone can help me..

i juz compile my code and have warning said that my coding have deprecated api and unchecked operation..and after compile back using command -Xlint: deprecation and -Xlint:unchecked

for -Xlint: deprecation

warning : [deprecation] toURL() in java.io.File have been deprecated

MyPlayer = Manager.createPlayer(((File)tmp.getFile()).toURL());

^

for -Xlint:unchecked

warning : [unchecked] unchecked call to add(E) as a member of the raw type java.util.ArrayList

arl.add ( r ) ;

^

for deprecation problem.. i think because rite now im using JDK 1.6.. previously jdk1.5.. and toURL was deprecated in jdk1.6.. so how to solve it?

for unchecked problem i have no idea

this is the full code
