A memory leak in a desktop application causes the application to become unresponsive after several hours of use. Which impact of the memory leak is most directly demonstrated?

Increased network bandwidth usage

Immediate application termination on startup

Degraded performance and eventual instability

How do static analysis tools detect potential memory leaks without executing the code?

By analyzing the source code or bytecode to identify paths where allocated memory is not released or references are not cleared.

By running the program with special instrumentation to track memory allocations and deallocations at runtime.

By monitoring the system's memory usage while the program is running and comparing it to a baseline.

By simulating the program's execution on a virtual machine to observe memory behavior.

Which of the following is a limitation of static analysis for detecting memory leaks?

It can only detect leaks that occur in a single-threaded program.

It can produce false positives because it cannot always determine whether a reference is truly no longer needed at runtime.

It can only detect leaks in interpreted languages, not compiled languages.

It requires the program to be run for a long time to accumulate enough memory usage data.
