named return variables

Learn named return variables in Solidity through a focused explanation, a dedicated construct-specific example, an engineering boundary, and a mastery check.

10 min read • Beginner

named return variables is an atomic Solidity topic inside Functions. This lesson focuses on how the named return variables construct is written, what it changes, and when it is the right tool.

Trace the example line by line. Identify the exact syntax for named return variables, the input state before it runs, and the resulting value, control flow, database state, hardware behavior, or runtime effect afterward. Neighboring lessons use different constructs rather than renamed copies of this one.

Topic-specific example

solidity-02-10-named-return-variables.sol
solidity Try It Live 
contract Calc { function divmod(uint a,uint b) external pure returns(uint q,uint r){ q=a/b; r=a%b; } }
Edge case / engineering note

For named return variables, test the boundary that belongs to this exact feature rather than a generic failure case. Check invalid or empty input, NULL/unknown state, numeric limits, transaction or exception behavior, synthesis/runtime constraints, ownership/permission rules, or backtracking/control-flow effects where they apply.
