Simple Storage Contracts Project

This project demonstrates the use of multiple Solidity smart contracts for storing, retrieving, and managing data on the Ethereum blockchain. It includes a SimpleStorage contract, a StorageFactory to deploy and manage multiple storage instances, and an Additive contract to handle basic arithmetic operations.

📁 Contracts

1. SimpleStorage.sol

A basic contract that allows users to store and retrieve a uint256 number.

Functions:

• store(uint256 _number): Stores a number.
• retrieve() view returns (uint256): Returns the currently stored number.

2. StorageFactory.sol

This contract allows deployment and management of multiple SimpleStorage contract instances.

Functions:

• createSimpleStorageContract(): Deploys a new SimpleStorage contract and tracks it.
• sfStore(uint256 _index, uint256 _number): Stores a number in a specific SimpleStorage instance by index.
• sfGet(uint256 _index) view returns (uint256): Retrieves a number from a specific SimpleStorage instance by index.

3. Additive.sol

A small utility contract that provides basic addition functionality.

Functions:

• add(uint256 a, uint256 b) pure returns (uint256): Returns the sum of two numbers.
