Free CPP: C Certified Professional Programmer Exam Questions and Answers
C Certified Professional Programmer is exam CPP, part of the C++ Institute certification programme from OpenEDG's C++ Institute. The C++ Institute is the sibling of the Python Institute — both are non-profit initiatives of OpenEDG — which is why their credentials look alike and are so often confused. It runs two language tracks rather than one: C++ through CPE at entry level, then CPA and CPP, and a parallel C track through CLE, CLA and CLP. CPA and CPP are both still actively offered, contrary to a fair amount of material that treats them as discontinued. The institute does not publish question counts, durations, pass marks or prices for them on its openly accessible pages.
The first 10 questions on this page are free to read, answers included — no account and no card. A plan opens the rest of the bank, the full timed practice test and your weak-topic reporting.

Was this answer correct?Question #2
You have an object of class Car. If Car contains a virtual destructor, what is its functionality?
Please select an optionIncorrectCorrect answer: B
A virtual destructor ensures that the destructor of derived classes is called when deleting a base class pointer.
Was this answer correct?Question #3
In a class hierarchy, why is using a const reference preferable for function parameters?
Please select an optionIncorrectCorrect answer: B
Const references avoid unnecessary copies, leading to improved performance, especially for large objects.
Was this answer correct?Question #4
If you overload the + operator for a class, what must it return?
Please select an optionIncorrectCorrect answer: B
An overloaded + operator must return an instance of the class to reflect the result of the addition operation.
Was this answer correct?Question #5
What happens if you neglect to declare your class methods as virtual in the base class?
Please select an optionIncorrectCorrect answer: D
If methods are not declared as virtual in a base class, derived classes cannot override them, leading to potential issues in polymorphism.
Was this answer correct?Question #6
In what scenario is it recommended to use std::move?
Please select an optionIncorrectCorrect answer: C
std::move is used to indicate that an object can be "moved from", facilitating resource transfer without deep copying.
Was this answer correct?Question #7
Why would you use std::unique_ptr instead of raw pointers in your code?
Please select an optionIncorrectCorrect answer: B
std::unique_ptr automatically manages the memory of dynamically allocated objects, ensuring safe and exception-proof ownership.
Was this answer correct?Question #8
How do you initialize a member variable with a member initializer list?
Please select an optionIncorrectCorrect answer: B
Member variables should be initialized in the member initializer list of constructors rather than in the constructor body to ensure proper construction order.
Was this answer correct?Question #9
Why should you avoid using global variables in C++?
Please select an optionIncorrectCorrect answer: A
Global variables can lead to naming conflicts and unintended modifications, decreasing code clarity and maintenance.
Was this answer correct?Question #10
A program needs to handle multiple exceptions. Which structure is more suitable?
Please select an optionIncorrectCorrect answer: B
Try-catch blocks are designed specifically for exception handling, allowing different types of exceptions to be managed effectively.
