Which of the following is a mechanism for removing multiple definitions of an identical template?

• A. Inheritance hierarchy
• B. Linker features
• C. Preprocessor directives
• D. Compiler optimizations

Answer: (B)

Linker features are a set of features that are performed after code is compiled and before it is linked into an executable. One of these features is the removal of multiple definitions of an identical template. This allows for more efficient use of memory and prevents potential errors. Inheritance hierarchy, preprocessor directives, and compiler optimizations are not mechanisms for removing multiple definitions of an identical template. Inheritance hierarchy is a programming technique used to create a new class from an existing class, but it does not specifically address the issue of duplicate templates. Preprocessor directives are instructions to the compiler that control the compilation process, but they do not directly handle duplicate templates. Compiler optimizations are techniques used to improve the performance of the compiled code, but they do not specifically target the removal of duplicate templates.
