Online Voting System in C

In this article, we will discuss the online voting system in C with its features, components, and code implementation.

Introduction:

In the era of digitalization, technology is ingrained in every facet of human existence, including election administration. Conventional paper-based voting methods have an assortment of drawbacks, such as difficult logistics, drawn-out ballot counting procedures, and the possibility of fraud or mistakes. Numerous nations are investigating the use of online voting technologies to solve these problems and enhance the efficacy and honesty of the election process.

The goal of the undertaking is to use the C programming language to create a prototype for an online voting system. We want to build a safe, straightforward-to-use platform that lets people cast ballots from the comfort of their own devices remotely by utilizing technology.

The Online Voting System's Features:

There are various features of the online voting system. Some main features are as follows:

User authentication: Users must securely recognize themselves before accessing the voting portion of the platform to ensure that only those who are eligible may take part in the electoral process.
Candidate Selection: A list of candidates to fill various posts will be shown to voters via the system. When casting a vote, users may study the biographies of the candidates to make an educated choice.
Casting a Ballot: After verifying their identity, voters can electronically cast their ballots by marking the names of the individuals whom they support. Each user will only be able to vote once, while the system will make sure that their choices are kept private.
Vote Tallying: As votes are cast, the system will instantly provide an update on the status of the election by tallying the outcomes in real-time.
Security features: The online voting platform will incorporate sophisticated safety features, such as encryption, authentication protocols, and tamper detection techniques, to protect the truthfulness of the electoral process.
Audit Trail: The system will keep a thorough record of every vote, allowing administrators to track and confirm the source of any vote and guarantee full transparency and accountability.

Obstacles and Things to Think About:

Creating an online voting system involves several difficulties as well as factors, such as:

Security: It is crucial to maintain the voting process's secrecy, integrity, and validity to thwart fraud, manipulation, or unintentional access.
Accessibility: The system must retain safety and usefulness while being usable and accessible to a wide variety of users, including those with impairments or low levels of technical knowledge.
Scalability: The system must be able to manage the increased workload as the number of candidates and voters rises without negatively impacting dependability or performance.
Regulatory Compliance: The online voting system must abide by all applicable laws, rules, and electoral standards to guarantee legal validity and acceptability.

User Interface (UI) Components:

The user interface (UI) component will be responsible for giving voters an easy-to-use interface through which to engage with the system. The listing of candidates, login screens, ballot casting screens, and result display screens are all included in this.
Text-based interfaces using libraries like ncurses or graphical interfaces with frameworks like GTK or Qt are examples of components for the User Interface.

Authentication System:

The authentication mechanism has confirmed voters' identities before they cast a ballot.

It might have login panels wherein users input their credentials (password and username) or implement more sophisticated methods of authentication like two-factor or biometric authentication.

Management of Candidates:

This component manages the list of candidates taking part in the voting process.

Administrators can use it to add, modify, or eliminate applicants using the database.

Voting Mechanism:

Voting and record-keeping are handled by the voting engine.

It ensures that votes are safely recorded and counted, and it stipulates that each voter may only cast one vote.

Vote validation, in which ballots are examined for validity before being accepted, is another function that the voting engine might manage.

Vote Tallying Methodology:

This part totalizes the votes that the voters have cast.

It totals the amount of ballots cast for every contender and determines the election's aggregate outcome.

The tallying system might also include features like report production and real-time outcome updates.

Database Administration:

Data about users, prospective employees, votes, and election outcomes are stored and managed via the information's database management component.

It guarantees dependability, security, and the accuracy of data.

SQLite and MySQL are two common databases used in C-based systems.

Features of Security:

Security features are necessary to ensure the confidentiality and integrity of the procedure for casting votes.

Sensitive data encryption, secure communication protocols (like HTTPS), and safeguards against manipulation or unwanted access are a few examples of this.

Audit Trail:

A reporting component records every important activity and incident within the system's structure.

It offers a thorough log of every user activity, such as voted cast, logins, and administrative operations.

Handling and Recording Errors:

This part manages exceptions and errors that could arise when the system is in use.

It logs error messages and diagnostic data to make troubleshooting and system maintenance easier.

Instruments for Administration:

The online voting system can be monitored and managed by authorized users with the help of administrative tools.

Features like a candidate and user administration, system configuration, and performance and health monitoring may be part of this.

Program:

Let us take a program to demonstrate the online voting system in C.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX_CANDIDATES 10
#define MAX_VOTERS 100

// Structure to represent a candidate
typedef struct {
    int id;
    char name[50];
    int votes;
} Candidate;

// Array to store candidate information
Candidate candidates[MAX_CANDIDATES];

// Function prototypes
void initializeCandidates();
void printCandidates();
void vote();
void showResults();

int main() {
    int choice;

    initializeCandidates();

    do {
        printf("\nOnline Voting System\n");
        printf("1. Vote\n");
        printf("2. Show Results\n");
        printf("3. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch(choice) {
            case 1:
                vote();
                break;
            case 2:
                showResults();
                break;
            case 3:
                printf("Exiting...\n");
                break;
            default:
                printf("Invalid choice. Please try again.\n");
        }
    } while (choice != 3);

    return 0;
}

// Initialize candidates with some sample data
void initializeCandidates() {
    candidates[0].id = 1;
    strcpy(candidates[0].name, "Candidate 1");
    candidates[0].votes = 0;

    candidates[1].id = 2;
    strcpy(candidates[1].name, "Candidate 2");
    candidates[1].votes = 0;

    // Add more candidates as needed
}

// Print the list of candidates
void printCandidates() {
    printf("\nList of Candidates:\n");
    for (int i = 0; i < MAX_CANDIDATES; i++) {
        if (candidates[i].id != 0) {
            printf("%d. %s\n", candidates[i].id, candidates[i].name);
        }
    }
}

// Function to cast a vote
void vote() {
    int choice;
    printCandidates();
    printf("Enter the candidate ID you want to vote for: ");
    scanf("%d", &choice);

    for (int i = 0; i < MAX_CANDIDATES; i++) {
        if (candidates[i].id == choice) {
            candidates[i].votes++;
            printf("Vote cast successfully!\n");
            return;
        }
    }

    printf("Invalid candidate ID. Please try again.\n");
}

// Function to display voting results
void showResults() {
    printf("\nVoting Results:\n");
    for (int i = 0; i < MAX_CANDIDATES; i++) {
        if (candidates[i].id != 0) {
            printf("%s: %d votes\n", candidates[i].name, candidates[i].votes);
        }
    }
}
