Which action should you take?

Choose only one option

It allows testing under controlled conditions, replicating real-world environments

It reduces the need for real-world testing

It simplifies the coding process

It eliminates all risks in development

Question 2: What is the significance of "Static Analysis" tools in C/C++ for aerospace software development, and how do these tools help ensure software reliability?

Which action should you take?

Choose only one option

Static analysis tools are only useful for testing the final product, not during development

Static analysis tools cannot detect issues in real-time systems

Static analysis tools detect potential coding errors, vulnerabilities, and compliance issues early, improving software reliability

Static analysis tools are irrelevant for aerospace software development
