Solidity

Solidity is an object-oriented, high-level language for implementing smart contracts. Smart contracts are programs which govern the behaviour of accounts within the Ethereum state.

Solidity is a curly-bracket language designed to target the Ethereum Virtual Machine (EVM). It is influenced by C++, Python and JavaScript.

Solidity is statically typed, supports inheritance, libraries and complex user-defined types among other features.

With Solidity you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets

Comments

Solidity supports both C-style and C++-style comments, Thus −

Any text between a // and the end of a line is treated as a comment and is ignored by Solidity Compiler.

Any text between the characters /* and */ is treated as a comment. This may span multiple lines.

Example:-

The following example shows how to use comments in Solidity.

// SPDX-License-Identifier: GPL-3.0
 
pragma solidity >= 0.7.0 < 0.9.0;

contract LearnComments {

   function getResult() public view returns(uint){
      // This is a comment. It is similar to comments in C++
   
      /*
         * This is a multi-line comment in solidity
         * It is very similar to comments in C Programming
      */
      uint a = 1;
      uint b = 2;
      uint result = a + b;
      return result;
   }

}
