  Here's a more complex example: pragma solidity ^0.8.0; contract MyToken { string public name; string public symbol; uint256 public totalSupply; mapping(address => uint256) public balanceOf; constructor(string memory _name, string memory _symbol, uint256 _totalSupply) { name = _name; symbol = _symbol; totalSupply = _totalSupply; balanceOf[msg.sender] = _totalSupply; } function transfer(address _to, uint256 _amount) public { require(balanceOf[msg.sender] >= _amount, 'Insufficient balance'); balanceOf[msg.sender] -= _amount; balanceOf[_to] += _amount; } }
