help with program errors for savings account program

[dariusd7]

Hi I am having trouble figuring out why i am getting the following error when I run the program. I am getting this error

51 II\FinalProjectSavingAccount.cpp [Warning] passing `double' for converting 1 of `SavingsAccount::SavingsAccount(int)'

[EtDecius]

SavingsAccount saver1(2000.00);
SavingsAccount saver2(3000.00);

For the first message, you're passing a double value here, but the constructor expects an int.

For the second message, it looks like there's a closing brace missing at the end of the main function.

Thanks ETDecius.. That work.

.but now I want to do it in oop format.. when I did i got the following errors

The error message basically says that you misspelled "#include" (you wrote "#inclue"). The typo is probably in the first few lines of savingsAccount.h that you neglected to show.

Random Note:
Your constructor takes in a double as a parameter, but your data member is a float, so you will lose precision in the conversion. Be consistent with your data types.
