Please write the following bank program in C++ with comments added when necessary.

Write a program that calculates the ending balance of several savings accounts. The program reads information about different customers' accounts from an input file, "accounts.txt". Each row in the file contains account information for one customer. This includes: the account number, account type (premium, choice, or basic account), starting balance, total amount deposited, and total amount withdrawn. Your program should: -open the file and check for successful open, then calculate the ending balance for each customer account. The calculated data must be saved in an output file, "accountsOut.txt", in a neat format as shown below. You may assume that the interest is 5% for premium' accounts, 3% for choice accounts, and 1% for basic accounts. You MUST use a named constant for the interest rates. Since the results displayed are monetary values, your output must be displayed with two decimal places of precision. Be sure decimals line up" when you output the final accounts information. And do not forget to close the files when done with them.
