Problem 7. Design an algorithm that will produce a savings account balance report from a customer savings account file. Each input savings account record contains the account number, balance forward, deposits (sum of all deposits) , withdrawals (sum of all withdrawals), and interest earned. Your program is to read the savings account file and print a detail line for each savings account record showing account number, balance forward, deposits, withdrawals, interest earned and final account balance. The final account balance is calculated as balance forward + deposits – withdrawals + interest. A heading is to appear at the top of each page and allowance is to be made for 45 detail lines per page. At the end of the report, print the total balances forward, total deposits, total withdrawals, total interest earned and total final account balances. 7C. Solution algorithm

Answer 1

It looks like a very good start for the pseudocode.

I would give the following comments:
1. include the definition of variables at the beginning of the pseudocode, as well as the type (int, double, etc.). If necessary, give a description.
2. You have included a lot of details of reading and printing, that is good.
3. Give the exact operations you plan to do with the variables, example,
- for a deposit, add the amount to the account balance.
- for a withdrawal, verify if the withdrawal exceeds the balance. If exceeded, print a message to that effect and cancel the withdrawal.
If the amount is not exceeded, proceed with the withdrawal (i.e. deduct the withdrawal amount from the account balance).
These checks should be done BEFORE each transaction is processed.

Also, it will help reading if you make a distinction between comments
"Read savings_account_record" is a comment, and
"Get final_account_balance "
is a computer executable statement.
You can put REM before comments (as in VB) or // (as in Java).
