I am developing a c++ banking system.
I am able
to get the float, newbal, values correctly and when I try
to write
to file, there is no data in the file.
else
{
file>>firstname>>lastname;
cout<<endl<<firstname<<" "<<lastname<<endl;
cout<<"-----------------------------------\n";
string line;
while (getline(file, line))
{
//stringstream the getline for line string in file
istringstream iss(line);
if (iss >>
date >> amount)
{
cout<<date<<"\t\t$"<<showpoint<<fixed<<setprecision(2)<<amount<<endl;
famount+=amount;
}
}
cout<<"Your balance is $"<<famount<<endl;
cout<<"How much would you like
to deposit today: $";
cin>>amountinput;
float newbal=0;
newbal=(famount+=amountinput);
cout<<"\nYour new balance is: $"<<newbal<<".\n";
file<<date<<"\t\t"<<newbal; //***This should be writing
to file
but it doesn't.
file.close();
The text file looks like this:
Tony Gaddis
05/24/12 100
05/30/12 300
07/01/12 -300
//Console Output looks like this
Tony Gaddis
05/24/12 100
05/30/12 300
07/01/12 -300
Your balance is: #1
How much wuld you like
to deposit: #2
Your new balance is: #1 + #2
write
to file
close file.
//exits
to main loop::::
How can I make it write
to file and save it, and why is this happening.
I tried doing it with ostringstream as well considering how I used istringstream for the input. But it didn't work either :\
float newbal=0;
newbal=(famount+=amountinput);
ostringstream oss(newbal);
oss<<date<<"\t\t"<<newbal;
I am trying
to self teach c++ so any relevant information would be kindly appreciated.
