To organize source code for maintainability, apply a conventional content order—such as file description, includes, constants, enums, types, imports, and class contents—to boost readability and speed up routine lookup.

Structuring a legacy codebase involves enforcing routine separation within files using blank lines and applying a consistent ordering strategy for related routines to improve code comprehension and navigation.

Separate routines within multi-routine C++ files by inserting blank-line separations between blocks and organizing related routines in a consistent alphabetical or logical order to speed lookup.

This code structure convention works for teams by enforcing boundary rules for routine separation and a standardized file content order, providing maintainable conventions across multi-routine files and legacy codebases.

C++ source file contents should follow a conventional order: file description, includes, constants, enums, types, imports, and class contents, which enforces clear structure and improves long-term maintainability.

Code structure refactoring becomes difficult without routine separation because scattered routines make source files hard to navigate, requiring blank-line separations and consistent ordering policies to restore readability.
