Standard C++98 Banking System example with OOPS

[2kaud]

The issue is here

for (bankMap::iterator i = data.begin(); i != data.end(); ++i)
{
     Saving *sb = dynamic_cast<Saving *>(*i);
     Current *cur = dynamic_cast<Current *>(*i);
     FixedDeposit *fd = dynamic_cast<FixedDeposit *>(*i);

There are a couple of issues here. i is an iterator to a map class

typedef map<int, Account*> bankMap;
bankMap data;

which has first and second values - so *i doesn't make sense. If you want the map data (type Account*) then use i->second rather than *i.

The second issue is that Account is not a polymorphic type so using dynamic_cast<> here is not allowed. The classes Saving, Deposit and FixedDeposit are derived from Account but are not polymorphic classes. For more info about polymorphism see http://www.cplusplus.com/doc/tutorial/polymorphism/
