Static analysis cannot find _____

  1. the use of a variable before it has been defined

  2. unreachable code

  3. memory leaks

  4. array bound violations


Correct Option: C

AI Explanation

To answer this question, you need to understand the concept of static analysis.

Static analysis is a method of analyzing code without actually executing it. It is used to find potential issues and errors in code by examining the code structure, syntax, and other static properties.

Let's go through each option to understand why static analysis can or cannot find it:

Option A) The use of a variable before it has been defined - Static analysis can indeed find this issue. It can analyze the code and identify any instances where a variable is being used before it is declared or assigned a value.

Option B) Unreachable code - Static analysis can find unreachable code. It can analyze the code and identify any sections of code that will never be executed due to conditional statements or other control flow structures.

Option C) Memory leaks - Static analysis cannot find memory leaks. Memory leaks occur when dynamically allocated memory is not properly released, leading to a loss of memory resources. Static analysis focuses on analyzing code structure and syntax, but it does not have the ability to track memory usage and identify memory leaks.

Option D) Array bound violations - Static analysis can find array bound violations. It can analyze the code and identify any instances where array elements are being accessed outside the valid bounds of the array.

Therefore, the correct answer is C) Memory leaks. Static analysis cannot find memory leaks as it does not have the capability to track memory usage and identify memory leaks.
