by Creating a Voting Management System in C++ using file handling involves tasks like registering voters, storing their information in files, allowing them to vote, and tallying the votes. Below is a basic example of a simple voting management system in C++ using file handling:
The Code I am going to share here is unique because IDs are fixed, ranging from 5555 to 5755. Any ID that is once used can’t be used again because it gets removed from IDs file.
Functions in the Code
Enter your name and ID
Cast Vote
View Results
Used File Handling
Code:
/*voting management System using file handling in C++
maximum vote can be casted : 200
*/
//any ID that is entered once can’t be added again
#include<iostream>
#include<fstream>
#include<conio.h>
using namespace std;
//ID’s.txt file for matching ID of the user
//vote_casted_ID.txt file containing ID’s that have been used to cast vote
int main()
{
cout<<“\n\tVOTING MANAGEMENT SYSTEM\n”;
string name;
int i,j,ID;
bool Id_exist=0;
//ID must be 4 digit number starting from 5555 ending at 5755
fstream file;
file.open(“ID’s.txt”,ios::in);
