Working with variables

contract WorkingWithVariables {

    uint256 public myUint;
    
    function setMyUint(uint _myUint) public {
        myUint = _myUint;
    }
    
    bool public myBool;
    
    function setMyBool(bool _myBoll) public {
        myBool = _myBoll;
    }
    
// Solidity silently wrapping around. 
// If myUint8 = 0 and you click on incrementUint() results are 255 
    uint8 public myUint8;
    
    function incrementUint() public {
        myUint++;
    }
    
    function decrementUint() public {
        myUint--;
    }
    
}

• In Solidity you don’t need a getter function, all function are having a getter function by default.

We can create a special getter function if needed in this way:

contract WorkingWithVariables {
    
    address public myAddress;
    
    function setAddress(address _address) public {
        myAddress = _address;
    }
    
    function getBalanceOfAddress() public view returns(uint) {
        //In Wei
        return myAddress.balance;
    }
}
