   A test analyst is reviewing a code review checklist for a C project. The team wants to prevent wild pointer defects. Which item should be added to the checklist to address the most common cause of wild pointers?

   • AEnsure that all pointers are declared as `const` where possible
   • BConfirm that all pointers are cast to the correct type
   • CCheck that all pointer arithmetic is performed on array elements
   • DVerify that all pointers are initialized before their first use

   • BComparing two pointers with relational operators
   • CAdding an integer to a pointer that points to a single variable
   • DSubtracting two pointers that point to different arrays

   A test analyst is configuring a static analysis tool for a project that uses a custom memory allocator. The tool reports many false positives for wild pointers because it does not understand the custom allocator's semantics. The team wants to reduce false positives without losing real defect detection. What is the most effective approach?

   • AUse dynamic analysis instead of static analysis to avoid the false positives
   • BSwitch to a different static analysis tool that is known to handle custom allocators
   • CConfigure the static analysis tool with annotations or models for the custom allocator
   • DDisable all wild pointer checks in the static analysis tool

   A test analyst is using AddressSanitizer to test a C++ application. The tool reports a heap-use-after-free error at a specific line of code. The analyst needs to determine the root cause of the defect. What is the most likely cause of this error?

   • AThe code reads beyond the end of a stack-allocated array
   • BThe code leaks memory because it does not call `delete`
   • CThe code writes to a null pointer
   • DThe code accesses memory that was previously freed with `delete` or `free`
