Error while sending an address to functions

Question

I am new to solidity and I have written some functions by referring to blogs and documentation. In one function, I must pass an address to send tokens to it. I have written the code for it but when I run it, I get the following error:

Invalid type for argument in a function call. Invalid implicit conversion from address to address payable request

Here is my code:

address admin;

function endSale() public {

 require(msg.sender == admin);

 selfdestruct(admin);

}

How to solve this?

Could you please mention the solidity version?

version is 0.5.0

Answer 1

In solidity 0.5.0 (and above) there are two datatypes for address: address and payable address. In these versions of solidity, you can send tokens only to address declared as payable, so change the address to address payable and it should work.

address payable admin;
