Quiz for Compile-time polymorphism

Q1: What is compile-time polymorphism?

A. Polymorphism resolved during compilation B. Polymorphism resolved during runtime C. Polymorphism using virtual functions D. Polymorphism using inheritance

Q2: Which of the following is an example of compile-time polymorphism?

A. Function overloading B. Virtual functions C. Abstract classes D. Interfaces

Q3: What mechanism does C++ use for compile-time polymorphism?

A. Function overloading and operator overloading B. Virtual function dispatch C. Abstract class methods D. Interface methods

Q4: Is compile-time polymorphism faster than runtime polymorphism?

A. Yes, because resolution happens at compile time B. No, runtime is faster C. Both are equally fast D. Depends on compiler

Q5: Can compile-time polymorphism be achieved with virtual functions?

A. No, virtual functions are runtime polymorphism B. Yes, always C. Only in templates D. Only in abstract classes

Q6: Which keyword is NOT associated with compile-time polymorphism?

A. virtual B. inline C. operator D. function

Q7: Does function overloading require different parameter lists?

A. Yes, different signatures are required B. No, same signature allowed C. Only different return type D. Only different const qualifier

Q8: Is operator overloading a form of compile-time polymorphism?

A. Yes, it is B. No, it is runtime polymorphism C. Only in templates D. Only in base classes

Q9: Which of these is NOT a benefit of compile-time polymorphism?

A. Faster execution B. Type safety C. Reduced runtime overhead D. Dynamic method dispatch

Q10: What happens if two overloaded functions have the same signature?

A. Compilation error due to ambiguity B. Compiler picks the first C. Compiler picks the last D. Overloading allowed

Q11: Can templates be considered compile-time polymorphism?

A. Yes, templates generate code at compile time B. No, templates are runtime C. Only in C++11 and later D. Only for classes

Q12: Is name mangling related to compile-time polymorphism?

A. Yes, it supports function overloading B. No, unrelated C. Only for virtual functions D. Only for templates

Q13: Which of these cannot be overloaded in C++?

A. Keywords like if and while B. Operators like + C. Functions D. Constructors

Q14: Can you overload a function based on return type alone?

A. No, return type does not affect overloading B. Yes, always C. Only for virtual functions D. Only for templates

Q15: What is required for operator overloading?

A. Overload the operator as a function B. Change operator precedence C. Create new operators D. Remove old operators

Q16: Can constructor overloading be an example of compile-time polymorphism?

A. Yes, constructors can be overloaded B. No, only normal functions C. Only destructors D. Only static functions

Q17: Which of these is true about compile-time polymorphism?

A. It provides static binding B. It requires virtual keyword C. It happens at runtime D. It is less efficient

Q18: Does compile-time polymorphism support dynamic behavior?

A. No, dynamic behavior needs runtime polymorphism B. Yes, always C. Only with templates D. Only with virtual functions

Q19: Which concept allows multiple functions with the same name but different parameters?

A. Function overloading B. Function overriding C. Virtual functions D. Abstract functions
