I am new to solidity and I have been trying to print out simple messages using functions in solidity, but I have failed to deploy successfully, and there is an error that I can not figure out what's wrong.
This is what I have tried so far:
pragma solidity ^0.6.0;
contract test {
string public _feedback;
function reply(string memory feedback) public
{
feedback = "Well done!";
}
}
The error I am receiving is "Warning: Function state mutability can be restricted to pure function"
