What is the purpose of the solc tool?

1. A tool for deploying smart contracts on Ethereum

2. A command line compiler for Solidity code

3. A testing framework for dApps

4. A security auditing tool

The correct answer is: A command line compiler for Solidity code

The solc tool serves a vital role in the Ethereum development ecosystem as it is specifically designed to compile Solidity code into bytecode, which can be executed on the Ethereum Virtual Machine (EVM). This tool translates human-readable Solidity source code into a format that the blockchain can process, enabling developers to create smart contracts that are functional and executable on the Ethereum network. This function of compiling is crucial for developers because it bridges the gap between the high-level Solidity programming language, which is designed for ease of understanding, and the lower-level bytecode that the EVM can understand. By using solc, developers can compile their code, ensuring that syntax and other language-specific errors are caught during the development process, thus streamlining the workflow and reducing the time spent debugging code before deployment. The other choices describe different functionalities not provided by the solc tool. While deploying smart contracts, testing, and auditing are all important aspects of the development process, they are managed by different tools and frameworks specifically designed for those tasks. Therefore, the primary and vital purpose of the solc tool remains its role as a compiler for Solidity code.
