    Which operation causes storage slot re-packing?

    Tip: Click "Play" to reveal options and start playing.

    #A
    #B
    #C
    #D
    Explanation:
    Changing variable types alters how Solidity packs them into storage slots. This can shift offsets and corrupt existing storage layouts in upgradeable contracts.

    Which Solidity construct enforces compile-time immutability?

    Tip: Click "Play" to reveal options and start playing.

    #A
    #B
    #C
    #D
    Explanation:
    constant variables are evaluated at compile time and embedded directly into contract bytecode. This guarantees immutability and avoids any runtime storage access or gas cost.

    Which Solidity keyword prevents state variable shadowing?

    Tip: Click "Play" to reveal options and start playing.

    #A
    #B
    #C
    #D
    Explanation:
    The override keyword forces explicit acknowledgment when a derived contract replaces a parent variable or function. This prevents accidental state variable shadowing in inheritance hierarchies, which can otherwise lead to subtle storage corruption bugs.

    Why is calldata preferred for router functions?

    Tip: Click "Play" to reveal options and start playing.

    #A
    #B
    #C
    #D
    Explanation:
    Calldata avoids copying user inputs into memory, significantly reducing gas usage for large payloads. Router contracts receive untrusted inputs, so avoiding memory expansion is both cheaper and safer. This is why AMMs and DEX routers heavily rely on calldata
