Free CPA-21-02: CPA – C Certified Associate Programmer Exam Questions and Answers
CPA – C Certified Associate Programmer is exam CPA-21, 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.
