Solidity Foundations

Identify and use Solidity value types: uint, int, bool, address, and bytes.

Declare and differentiate between state variables, local variables, constants, and immutables.

Write functions with appropriate visibility specifiers (public, external, internal, private).

Use control flow constructs (if/else, for loops, while loops) in Solidity.

Explain and correctly use storage, memory, and calldata data locations.

Define and use structs and enums to model domain data.

Declare and manipulate arrays and mappings.

Handle errors using require, revert, and assert with appropriate use cases for each.
