Hi there,
I was hoping for some advice on how best to solve my problem.
I'm creating a .csv file to store objects in, but the datamembers which are strings, require the ability to have commas within the strings.
I have found out that I therefore need to enclose the fields in the .csv file within double quotes.
So I am trying to write a function to add double quotes to the beginning and the end of each string.
This is what I have come up with so far:
I have enclosed the relevant parts with comments like this:
//XXXXXXXXXXXXXXXXX
Header file (diary.h) :
using namespace std;
#include <string>
class Diary
{
public:
Diary(string mainname, string mainaddress, string mainpostcode, string maintelno, string maindetails);
//Getters (Getters are used to access private or protected datamembers) :
string getName() const { return m_Name; }
string getAddress() const { return m_Address; }
string getPostCode() const { return m_PostCode; }
string getTelNo() const { return m_TelNo; }
string getDetails() const { return m_Details; }
//Pure Virtual getter functions for Leads class
virtual string getDate() = 0;
virtual string getTime() = 0;
//XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
//Pure virtual function to add the double quotes to the .csv files fields
//virtual string addDoubleQuotes() = 0;
//XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
private:
protected:
string m_Name;
string m_Address;
string m_PostCode;
string m_TelNo;
string m_Details;
};
Diary::Diary(string mainname, string mainaddress, string mainpostcode, string maintelno, string maindetails)
{
m_Name = mainname;
m_Address = mainaddress;
m_PostCode = mainpostcode;
m_TelNo = maintelno;
m_Details = maindetails;
}
//----------------------------------------------------------------
class Leads : public Diary
{
public:
Leads(string m_Name, string m_Address, string m_PostCode, string m_TelNo, string m_Details, string m_Date, string m_Time);
//Getters:
string getTime() { return m_Time; }
string getDate() { return m_Date; }
private:
protected:
string m_Date;
string m_Time;
};
Leads::Leads(string mainname, string mainaddress, string mainpostcode, string maintelno, string maindetails, string maindate, string maintime) : Diary(mainname, mainaddress, mainpostcode, maintelno, maindetails)
{
m_Date = maindate;
m_Time = maintime;
//add the double quotes to the object here so that the programs
//other funtionality is possible, without the double quotes it may not be
//XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
//add double quotes to m_Name:
m_Name = addDoubleQuotes(m_Name);
//add double quotes to m_Address:
m_Address = addDoubleQuotes(m_Address);
//add double quotes to m_PostCode:
m_PostCode = addDoubleQuotes(m_PostCode);
//add double quotes to m_TelNo:
m_TelNo = addDoubleQuotes(m_TelNo);
//add double quotes to m_Details:
m_Details = addDoubleQuotes(m_Details);
//add double quotes to m_Date:
m_Date = addDoubleQuotes(m_Date);
//add double quotes to m_Time:
m_Time = addDoubleQuotes(m_Time);
//XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
}
Leads::addDoubleQuotes()
{
//XXXXXXXXXXXXXXXXXXXXXXXXXX
//add the double quotes here
//XXXXXXXXXXXXXXXXXXXXXXXXXX
return 0;

int choice = 0;

cin.ignore();
switch(choice)

{

}
catch (bad_alloc& ba)
{
cerr << "bad_alloc caught: " << ba.what() << endl;
}
cout << "past push Lead to list and before deletion" << endl;
break;
}
case 2:
{
cout << "You chose to exit the program" << endl;
ofstream streamname("database.csv");
if(!streamname)
{
cout << "Cannot open file" << endl;
return 1;
}
for(unsigned int a = 0; a<vectorname.size(); a++)
{
streamname << vectorname[a]->getName() << "," << vectorname[a]->getAddress() << "," << vectorname[a]->getPostCode() << "," << vectorname[a]->getTelNo() << "," << vectorname[a]->getDetails() << "," << vectorname[a]->getDate() << "," << vectorname[a]->getTime() << endl;
}
for(unsigned int a = 0; a<vectorname.size(); a++)
{
delete vectorname[a];
}
streamname.close();
exit(0);
break;
}
}
}
while(true);
system ("PAUSE");
return 0;
}Sorry for the large block of code, but I hoped it may help explain what it is I'm trying to do.
I was wondering if I'm going in the right direction with this.
My first problem, which is why I'm here, is that I plan to pass each field (m_Name, m_Address etc) to the function, but am unsure of how to pass this string to the function without having to write a separate function for each string modification (ie: add the double quotes to the field).
Maybe I should be approaching the problem another way.?
As you may gather, I'm a little lost with this right now, so any help is really most appreciated!
Many thanks.
Carrots :)
