    • Calculate the service charge.
  • Call the function “monthlyProc()”.
  • Call the function “getMonthlyStats()”

Checking.h:

• Define the “ Checking.h”.

• Declare the functions “withdraw()”, “deposit()” and “monthlyProc()”.

Account.h:

• Define the “Account.h”.
• In protected, declare the required variables.
• In public, invoke the constructor. And declare the functions “withdraw()”, “deposit()” and “monthlyProc()”.

Account.cpp:

• Create a constructor “Account()” and initialize the variables.
• Function definition for “deposit()” of Account class.
  • Add the “amount” with the “bal” amount.
  • Increment the “dep_amt”.
• Function definition for “withdraw” of Account class.
  • Subtract the “amount” with the “bal” amount.

  • Display the withdraw amount, deposit amount, service charges and ending balance.

Soruce.cpp:

• Include the required header files.
• Define the main() function,
  • Include the required function prototype to the program.
    • Create an object for savings and checking.
    • Declare a variable to hold the user choice.
    • Display the menu options.
    • Validate the menu options.
    • Execute the user’s choice.
    • Use switch for selecting options.
      • Case 1:
        • Get the deposits amount.
        • Call the “deposit()” from the savings class.
      • Case 2:
        • Get the deposits amount.

        • Get the withdraw amount.
        • Call the “withdraw()” from the checking class.
      • Case 5:
        • Call the “ignore()” then call the “monthlyProc()” from the savings class.
        • Call the “get()” then call the “monthlyProc()” from the checking class.
