Question

Which one of the following is NOT performed during compilation?

Correct answer (A) Dynamic memory allocation Solution 1. Dynamic memory allocation : This occurs at runtime (e.g., using malloc in C or new in C++). The compiler generates code to perform this, but the actual allocation happens when the program is running. 2. Type checking : This is a phase of the compiler (Semantic Analysis) where it checks for type errors. 3. Symbol table management : The compiler maintains a symbol table to keep track of variables, functions, and their attributes throughout the compilation process. 4. Inline expansion : This is an optimization technique performed by the compiler where function calls are replaced by the function body. Therefore, Dynamic memory allocation is not performed during compilation. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
