What is Solidity Programming Language?

Solidity is a statically typed programming language that is designed for developing smart contracts that run on Ethereum.

1. It is a contract-oriented and high-level programming language.
2. It supports complex programming features like inheritance, libraries, and user-defined data types, among other features.
3. It has syntax similar to that of JavaScript.
4. The file extension of the Solidity file is .sol.
5. It is used to create smart contracts for various purposes such as voting, muti-signature wallets, and many more.

Below is the Solidity program of the default code in the code editor:

Explanation:

1. SPDX License Identifier

// SPDX-License-Identifier: MIT

SPDX License Identifiers are standardized abbreviations for common open-source software licenses.

2. Version Pragma

pragma solidity >=0.6.12 <0.9.0;

Pragma are the instructions to the compiler on how to treat the code. This line states that the code is compatible with a version greater than or equal to 0.6.12 but less than 0.9.0.

3. The contract keyword

contract HelloWorld {

}

The contract keyword is used to declare a contract HelloWorld consisting of functions and data.

4. Function declaration

function print() public pure returns (string memory)

The print() function will print the string value on the console. The function has an access modifier public and is declared as pure as it does not read or modify the variables of the state.

5. Return statement

return “Hello World!”;

The return statement prints the string Hello World! on the console.

Smart contracts are self-execution programs stored on a blockchain that are automatically executed when predefined conditions are met. They allow the participants on the blockchain to transact with each other without a trusted central authority. After creating a smart contract, the next step is to deploy the smart contract onto a blockchain for execution. For this purpose, developers often use development tools such as Remix IDE. This article focuses on discussing steps to create, test, and deploy the Ethereum Smart Contract on Remix Tool.
