LowFunction Could Be Declared ExternalOpen

The functions which are never called internally within the contract should have external visibility for gas optimization. ```solidity=24 function transferOwnership(address newOwner) public onlyOwner { ``` --- ```solidity=38 function getUserRecord(address user) public view returns (uint num) { ``` --- ```solidity=42 function setUserRecord(address user, uint num) public onlyOwner { ``` --- ```solidity=47 function userSignIn() public { ``` --- ```solidity=51 function getMyRecord() public view returns (uint num) { ```

LowPotential integer overflowOpen

The number in `roster[msg.sender]` increases every time the user calls this function. The contract neither uses the safemath library nor solidity version 0.8.0, so the number can overflow.
