Type struct Mycontract.User memory is not implicitly convertible to expected type struct Mycontract.User storage pointer

Question

pragma solidity >=0.5.0 <0.7.0;
contract Mycontract{
    uint256 a;
    struct User
    {  string name; }
    User[] users;
    function foo() public{
      **User storage user=User("hey");**  
     users.push(user);
    }
    function get() public view returns(string memory)
    {   return users[0].name; }
}

However when the above highlighted statement changed to the below statement will solve the error:

 User memory user=User("hey");  

Can anyone explain the reason behind this changing from memory to storage?

Answer 1

Variable in contract by default are of storage, i.e. they are state variables. And new struct default allocation within function is memory.

Hence the compiler warning.
