Hi there, i have an assignment, and i need to create a monthly expenditure. I have managed to get alot done, a fully functioning menu and all the functions. Im stuck when it comes to deleting an entry
I have been using structured arrays to store data, ive posted all my code, i thought it be easier for help, sorry for the massive post.
#include "stdafx.h"
#include <iostream>
#include <string>
#include <stdlib.h>
#include <fstream>
using namespace std;
int i;
int count;
int userChoice;
string temp;
int newExpenses();
int newIncome();
void menuExpenses();
void menuIncome();
void mainMenu();
void monthlyExpenses();
void monthlyIncome();
void deleteEntry();
int main()
{
string line;
ifstream myfile ("counter.txt");
if(myfile.is_open())
{
while(!myfile.eof())
{
getline(myfile,line);
temp=line;
}
myfile.close();
}
count=atoi(temp.c_str());
do{
mainMenu();
}while(userChoice != 1 || userChoice != 2);
return 0;
}
struct entry{
int ID;
string date;
string item;
string price;
string category;
}entries[100];
void mainMenu()
{

void deleteEntry()
{
int choice;
int i;
cout<<"What entry do you wish to delete?: "<<endl;
cin>>choice;
if(choice >= 0 && choice <= 100)
{
for(i=choice;i<100;i++)
{
entries[i] = entries[i + 1];
}
}
else
{
cout<<"Invalid Entry";
}
}What my tutor suggested was to use a counter, and then save the counter also in a text file, so when i reopen the console, the counter doesnt reset to 0
Is there a simpler way to be able to delete one of these entries? each entry has an ID
