When debugging, what action would a developer take at a breakpoint?

When a developer encounters a breakpoint during debugging, the primary action taken is to step through the code. A breakpoint serves as a pause point in the execution of a program, allowing the developer to examine the state of the program at that particular moment. By stepping through the code, the developer can execute one line at a time, which enables them to closely monitor variable values, track the flow of execution, and identify any errors or unexpected behavior in the program.

This careful examination is crucial for diagnosing issues, as it provides insights into how the code is functioning in real-time. Observing the program's state and behavior in a controlled manner allows developers to pinpoint the exact location and cause of problems, facilitating effective troubleshooting and refinement of the code.

Other actions, such as continuing execution, changing the code, or running the program normally, do not offer the same level of granularity or control needed for effective debugging at a breakpoint.
