Any idea for the simplest way to add "degrees" variable into the string like below?
Looking for getString to return "today is 40 degrees outside".
pragma solidity ^0.5.3;
uint public degrees= 40;
function getString() public view returns(string memory){
string memory a = "today is ";
string memory b = degrees;
string memory c = "degrees outside";
string memory sentence = string(abi.encodePacked(a, b, c));
return sentence;
}
