Q2: Which C++ feature supports generic programming?

A. Templates B. Macros C. Inheritance D. Pointers

Q3: What is the benefit of generic programming?

A. Code reusability and type safety B. Faster compilation C. Reduced memory usage D. Easier debugging

Q4: Which STL component uses generic programming?

A. All containers and algorithms B. Only containers C. Only algorithms D. Only iterators

Q5: What does a template parameter represent?

A. A placeholder for a data type or value B. A function name C. A variable D. A keyword

Q6: Which of the following is a function template syntax?

A. template<typename T> void func(T a); B. void func<T>(T a); C. template func<T>(T a); D. function<T> void func(T a);

Q7: Can generic programming handle user-defined types?

A. Yes, as long as operations used are defined B. No, only primitive types C. Yes, but only with macros D. No, it causes errors
