Why do i ask this? I've been trying to solve this for hours.

Problem version 1:

Warning: Defining constructors as functions with the same name as the contract is deprecated. Use "constructor(...) { ... }" instead.function TokenERC20(

 */
function TokenERC20( 
    uint256 initialSupply,
    string tokenName,
    string tokenSymbol

Version 2

browser/Test.sol:187:6: Warning: Defining constructors as functions with the same name as the contract is deprecated. Use "constructor(...) { ... }" instead.

/* Initializes contract with initial supply tokens to the creator of the contract */
 function MyAdvancedToken(
    uint256 initialSupply,
    string tokenName,
    string tokenSymbol
) TokenERC20(initialSupply, tokenName, tokenSymbol) public {}

Listen to your warning!

constructor(
    ...
    ...

Its a new solidity thing...the argument that has the same name as the Contract no longer works, you have to use 'constructor'

These both codes, does seem to be annoying. I've been doing exactly that, but it just won't work. It seems alike that there's something that i Should now here.

*/ function TokenERC20( uint256 initialSupply, string tokenName, string tokenSymbol

function MyAdvancedToken( uint256 initialSupply, string tokenName, string tokenSymbol

  • the keyword is constructor, and you have to remove the contract name (in your case TokenERC20) please check this answer https://ethereum.stackexchange.com/questions/45972/ive-got-an-error-while-compiling-use-constructor-instead/45973#45973 – qbsp May 09 '18 at 02:30
