Manual Iteration
Manual iteration is a development approach where code is executed step-by-step by a developer using debugging tools or manual inspection to examine and modify program state, rather than relying on automated tests or batch processing. It involves techniques like setting breakpoints, stepping through code, and inspecting variables to understand and fix issues in software. This method is commonly used for debugging, exploring code behavior, and verifying logic in complex or unfamiliar systems.
Developers should use manual iteration when debugging specific, hard-to-reproduce bugs, understanding legacy code, or verifying the flow of complex algorithms where automated tools may not provide sufficient insight. It is essential in scenarios like troubleshooting runtime errors, testing edge cases interactively, or during exploratory programming to gain a deeper understanding of how code executes in real-time.
