Question
Create a C++ console application that will store and retrieve names and addresses in a text file.
The program should do the following.
It should accept a series of names and addresses from the console.
The user's input should be written to a text file in the CSV format described in the lecture, but do not include the field names in the first row of the file.
Read the records from the text file, and display them in a user-friendly format.
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
//Specification: Append and display records in a address database
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void menu(void);
void writeData(void);
void readData(void);
string * split(string, char);
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
}//end write data
void readData(void){
//read data from a file
//use the split function to break a
//deliminated line of text into fields
}//end read data
string * split(string theLine, char theDeliminator){
//Break theline into fields and save the fields to an array.
//Each field will occupy one element in a character array.
//theLine is a string with fields separated with theDeliminator character.
//Assumes the last field in the string is terminated with a newline.
//Useage: string *theFields = split(lineBuffer, ',');
//determine how many splits there will be so we can size our array
int splitCount = 0;
for(int i = 0; i < theLine.size(); i++){
if (theLine[i] == theDeliminator)
splitCount++;
}
splitCount++; //add one more to the count because there is not an ending comma
//create an array to hold the fields
string* theFieldArray;
theFieldArray = new string[splitCount];
//split the string into seperate fields
string theField = "";
int commaCount = 0;
for(int i = 0; i < theLine.size(); i++){ //read each character and look for the deliminator
if (theLine[i] != theDeliminator) {
theField += theLine[i]; //build the field
}
else { //the deliminator was hit so save to the field to the array
theFieldArray[commaCount] = theField; //save the field to the array
theField = "";
commaCount++;
}
}
theFieldArray[commaCount] = theField; //the last field is not marked with a comma...
return theFieldArray;
} //end split
Explanation / Answer
this program is for reading the records from the text file which is comma seperated
HOW TO RUN
save by filerecords.cpp
on terminal
g++ filerecords.cpp -std=c++11
./a.out
