You will code, build, and execute a program that requires sequential files to create an address database.

Learning Outcomes

1. Continue using a menu system with console applications.
2. Be able to write a console application.
3. Demonstrate entering, appending, storing, and retrieving records.
4. Be able to write lines of output to a text file in order to create a report.

Preparation:

If you are using the Citrix remote lab, follow the login instructions located in the lab area in Course Home.

Locate the Visual Studio icon and launch the application.

Lab:

Step 1: Requirements: An Address Database

Create a C++ console application that will store and retrieve names and addresses in a text file.

The program should do the following.

1. It should accept a series of names and addresses from the console.
2. The user's input should be written to a text file in the CSV format described in the lesson, but do not include the field names in the first row of the file. Use a delimiter to separate the records.
3. Read the records from the text file, and display them in a user-friendly format.
4. Provide a menu to allow the user to append records to the file, display the records, or exit the application.

Build upon the code below to complete the assignment.

//Specification: Append and display records in a address database

#include

#include

#include

using namespace std;

void menu(void);

void writeData(void);

void readData(void);

const char FileName[] = "TestAddress.txt";

int main () {

menu();

return 0;

} //end main

void menu(void) {

//allow user to choose to append records, display records or exit the program

}//end menu

void writeData(void){

//Write the Address Info to a file

//loop while user still has data to write to file

//eg outStream<

}//end write data

void readData(void){

//read data from a file

//use the split function to break a

//deliminated line of text into fields

ifstream inMyStream (FileName);

if (inMyStream.is_open()) {

//set character to use as a line between record displays

string recBreaks = "";

recBreaks.assign(20,'-');

int fieldCount = 0; //keep track of the number of fields read

int recordCount = 1; //keep track of the number of records read

//read the first field

fieldCount = 1;

string fieldBuffer;

getline (inMyStream, fieldBuffer, '#');

while (!inMyStream.eof() ){

//display the field

switch (fieldCount) {

case 1:

cout << recBreaks << endl;

cout << "record # " << recordCount << endl;

cout << "Name...." << fieldBuffer << endl; break;

case 2:

cout << "Street.." << fieldBuffer << endl; break;

case 3:

cout << "City...." << fieldBuffer << endl; break;

case 4:

cout << "State..." << fieldBuffer << endl; break;

case 5:

cout << "Zip....." << fieldBuffer << endl;

fieldCount = 0;

recordCount++; break;

}

//read the next field

getline (inMyStream, fieldBuffer, '#');

fieldCount++;

}

cout << recBreaks << endl;

inMyStream.close();

}//end read data

Step 2: Processing Logic

Using the pseudocode below, write the code that will meet the requirements.

The pseudocode for the writeData function is shown below.

Start

open the text file to append

start do while loop

Allow user to enter name

store name (using getline method)

Allow user to enter city

store city (using getline method)

.

.

write name, city, etc.to the file

end loop

close the file

End

The program input should appear similar to this.

Append Records

Name..........John Smith

Street.........902 Union Ave

City............Any Town

State...........TX

Zip Code......78552

"Enter another Record? (Y/N) "

The file structure should look like this.

John Smith, 902 Union Ave, Any Town, TX, 79552

Eric Jones, 345 State Way, Fresno, CA, 93432

...

The file output should appear similar to the following.

Show Records

__________________________________________

Record #1

Name...........John Smith

Street..........902 Union Ave

City.............Any Town

State...........TX

Zip Code......78552

__________________________________________

Record #2

Name...........Eric Jones

Street..........345 State Way

City.............Fresno

State...........CA

Zip Code.......93432

__________________________________________

(A)ppend Records, (S)how Records, (E)xit

Step 3: Create a New Project

Create a new project and name it LAB7. Write your code using the processing logic in Step 2. Make sure you save your program.

Step 4: Compile and Execute

1. Compile your program. Eliminate all the syntax errors.

1. Build your program and verify the results of the program. Make corrections to the program logic, if necessary, until the results of the program execution are what you expect.

Step 5: Print Screenshots and Program

1. Capture a screen print of your output. (Do a print screen and paste into an MS Word document.)
2. Copy your code and paste it into the same MS Word document that contains the screen print of your output.
3. Save the Word document as Lab07_LastName_FirstInitial.
