Hey guys, I'm currently developing an application in C++ called "Merchant Logger". It's quite hard to build but right now I'm aiming for these things:
-Successfully reads/writes information and displays it to the console.
-Can delete and add logs
-Stores item name, date, selling and buying price
Future goals if people like it:
-Cross platform GUI
-Will calculate overall earned (might add it to V1)
-More stuffs and ease of use.
I'll be posting my progress in a different section however.
8/25/2011:
Program works, but having trouble enabling it to append text rather than completely overwrite the database.
Fix the appending text! Woot! Now working on a calculations system, going to be rather difficult.
I decided to dump the current way I've been doing it and go for a much more elegant design. Old design source:
It's very ugly, so I'm currently looking at V.02.

Code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
using std::ifstream;
using std::ofstream;
string currentCommand;
string tableName = "Log1";
//string CalcLogName;
struct addTable {
string name;
string date;
string item;
int buy;
int sell;
};
int main () {
rerun:
char contents;
fstream MerchLog ("Merch_Log.txt", ios::in | ios::out | ios::app); //opens Merch_Log for read/write capabilites
if (MerchLog.is_open()) { //executable code if merch is open
cout << "Please input a command (help)\n";
cin >> currentCommand;
if (currentCommand == "tables") {
cout << tableName << "\n";
goto rerun;
}
if (currentCommand == "help") {
cout << "Commands are:\n";
cout << "display -- displays contents of Merchant Log\n";
cout << "help -- display lists of commands\n";
cout << "write -- adds a new entry to the log\n";
cin >> currentCommand;
}
if (currentCommand == "display") { //displays contents
for (int i = 0; i<4; i++) {cout << "\n";}
MerchLog.get(contents); //gets first character
while (!MerchLog.fail() && !MerchLog.eof()) {
cout << contents;
MerchLog.get(contents);
}
goto rerun;
}
if (currentCommand == "write") {
//addTable Log;
//string name, date, item, buy, sell;
cout << "Table Name (this won't show, just gives new list a unique table): ";
cin >> tableName;
addTable tableName;
cout << "Log Name: ";
cin >> tableName.name;
cout << "Date: ";
cin >> tableName.date;
cout << "Item Name: ";
cin >> tableName.item;
cout << "Buying Price: ";
cin >> tableName.buy;
cout << "Selling Price: ";
cin >> tableName.sell;
MerchLog << tableName.name << " | "<< tableName.date << " | " << tableName.item << " | " << tableName.buy << " | " << tableName.sell << endl;
MerchLog.close();
goto rerun;
}
if (currentCommand == "calculate") {
cout << "Table Name: ";
cin >> tableName;
return tableName.buy;
}
cin >> currentCommand;
}
//ofstream CreateLog ("Merch_Log.txt");
goto rerun;
}
/*Problem: New input is changing values of old input, find a way to make unique input everytime l:46*/It's very ugly, so I'm currently looking at V.02.
