Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: Higher cyclomatic complexity indicates a more complex program. Reason R: It is calculated based on the number of independent execution path in the program. In the light of the above statements, choose the most appropriate answer from the options given below
The question asks us to evaluate two statements, Assertion A and Reason R, related to cyclomatic complexity.
Analyzing Assertion A: Program Complexity
Assertion A states that higher cyclomatic complexity indicates a more complex program. This is correct. Cyclomatic complexity is a quantitative measure of the complexity of a program. A higher number generally suggests more control flow paths, making the code harder to test, understand, and maintain.
Analyzing Reason R: Calculation Basis
Reason R states that cyclomatic complexity is calculated based on the number of independent execution paths in the program. This is also correct. Cyclomatic complexity specifically measures the number of linearly independent paths through a program's source code. It's often calculated using control flow graphs.
Connecting Assertion A and Reason R
Since a higher number of independent execution paths (as stated in Reason R) directly leads to a more complex structure and thus a more complex program (as stated in Assertion A), Reason R provides the fundamental basis for Assertion A. Therefore, Reason R is a correct explanation of Assertion A.
Based on this analysis:
- Assertion A is correct.
- Reason R is correct.
- Reason R is the correct explanation of Assertion A.
This aligns with Option A.
