Solidity error SyntaxError No visibility specified

Question

I have this piece of code:

  constructor() {

                caller = msg.sender;

  }

When I compile it, I am getting this error:

browser/vote.sol:17:3: SyntaxError: No visibility specified. Did you intend to add "public"? 

constructor() { ^ (Relevant source part starts here and spans across multiple lines).

How to solve this?

Answer 1

As mentioned in the error, you have to mention the visibilty. If you wanna add public, you can do it like this:

constructor() public {

                caller = msg.sender;

  }
