Which of the following is incorrect with respect to Model Checking ?
Which of the following is incorrect with respect to Model Checking ?
A. Model checking is particularly valuable for verifying concurrent systems
B. Model checking is computationally very inexpensive
C. The model checker explores all possible paths through the model
D. All of the mentioned
Explanation: Model checking is very expensive.It is only practical to use it in the verification of small to medium sized critical systems.

Which level of Static Analysis allows specific rules that apply to a program to be checked ?
Which level of Static Analysis allows specific rules that apply to a program to be checked ?
A. Characteristic error checking
B. User-defined error checking
C. Assertion checking
D. All of the mentioned
Explanation: Users of a programming language define error patterns, thus extending the types of error that can be detected.
