Online Polling Canister

This project is a canister developed for the Internet Computer Protocol (ICP) using the Azle framework. It provides a simple yet effective way to create and manage online polls, allowing users to create polls, vote on them, view results, and delete polls.

Key Components

• PollOption: A record that represents a single option in a poll, including the option text and the number of votes it has received.
• Poll: A record that represents a poll, including its unique identifier, the question being asked, a list of options, and a flag indicating whether the poll is active.
• pollStorage: A StableBTreeMap used for stable storage, ensuring the persistence of polls across system updates.

Features

• createPoll: Create a new poll with a question and a list of options.
• vote: Cast a vote in a poll for a specific option.
• getPollResults: Retrieve the current results of a poll, including the number of votes for each option.
• deletePoll: Delete a poll from the system.
• listActivePolls: List all active polls currently available for voting.

Interaction

Users can interact with the canister through its public methods. The canister supports both reading and writing operations, enabling users to participate in polls and view real-time results.

Purpose

This canister serves as a practical example of how to build and manage a basic polling system on the ICP using the Azle framework. It demonstrates handling user inputs, managing state, and querying data.

How to Run the Project
