Delete and default values

Why use this example

Use this pattern to explore how Solidity represents typed values and how state-changing expressions affect storage. The entry isolates delete and default values so its input, result, and state changes stay easy to compare.

Solidity to run

uint256 public answer = 42
bool public ready = true
delete answer
delete ready

answer
ready

Official Solidity reference

Compare this focused investigation with the complete language definition in the Solidity documentation.

What to expect

Deleting the state variables resets the uint256 to 0 and the boolean to false.

Continue the investigation

Change a value, add another expression, or open Inspect after the run. Accepted entries remain available to the next entry, and the clean replay keeps the complete result reproducible.
