Lab/Project Solution

1. Problem Statement




Given a struct clientData, build a program that can fill a file with instances of this data and read it back.




2. Requirements




2.1 Assumptions




Some of the code is provided on the “instruction” sheet.



Command Line Input Only



User will only enter integers where applicable



User will only enter doubles where applicable



2.2 Specifications




Struct clientData will be used



File will be accessed randomly



File will accommodate 100 user inputs



User can request specific accounts



Program will print out all used accounts in order

Method:



Open Output Stream



Name File “client.dat”



Iterate 100 Times



Fill with blankClient



Close Output Stream



Create Function writeToFile



Parameters: clientData client



Return: Void



Method:



Open Output Stream



Do While Account Number is not 0



Prompt for initial Account Number



IF 0



Exit Function



Else IF 1 = Account Number = 100



Fill First Name



Fill Last Name



Fill Balance



Seek Position of Account Number in file



Write client data to file



Else



Alert Invalid Account Number



Create Function userRead



Parameters: clientData client



Return: Void



Method:



Create Input Stream



Do While



Prompt for Account Number



IF input = 0



Return/Exit



Else IF 1 <= input <= 100



Seek Input



Read Input



IF Input != 0



Output Data



Else



Alert Invalid Account Number



Create Function printAllRecords
Parameters: clientData client



Return: Void



Method:



Create Input Stream



Read Initial Data



While inCredit && !inCredit @ End Of File



IF client.accountNumber != 0 a. Output Data



Read Next Data



Create MAIN



Create and Initialize client and blankClient as {0,””,””,0.0}



Perform createBlankFile(blankClient)



Perform writeToFile(client)



Perform userRead(client)



Perform printAllRecords(client)



Return 0;
