Accounting Program

CyphuricErodoll (2)
-Accounting program using a .txt file chosen at random by my professor
-The .txt file will have a list of made-up bank accounts with the three columns
in the format of bank account number(int), bank account user's last name(char?
he also suggested long might work to store their last name?), and the user's
balance (double).
-The exact lines of bank accounts will be random and the account
numbers/balance/lastnames will be random, but they will follow the same format
of account number, space/tab, last name, space/tab, and balance.
-The program asks the user to look up account by account number or last name.
-Account number lookup: this will display their last name and their balance.
-Lastname lookup: this will display their account number and their balance.
-The data read from the .txt file is stored in three parallel arrays.
-Sequential search used to find account number/lastname which the user types.
-If the user enters an account number/last name which is in the .txt file list,
the program saves the index and uses the index to look up the account number &
balance (or the last name and balance).
-And of course if the account number/last name is not found, the program says so.


The program thus far: There is a problem with the way it's reading the three types of input.

Proper indentation will help you troubleshoot common problems.

Thank you. The line I'm having problems with in particular, though, is

cin >> search_acct;

Does anybody possibly know what is wrong with the way the program reads in the data types?

I'm assuming you're on a Windows PC. Your issue is mixing cin and getline. Long story short, add this line of code after your getline call cin.ignore();

If you really care, you'll ask why. Or, better yet, you'll research it and understand why it's needed.
