80 C Trivia Questions with Answers
80 public questions with answers, drawn from the well. How many can you answer?
C trivia brings together questions from history, geography, science, astronomy, medicine, language, computing, and international affairs. The category can move from the Roman author who wrote De agri cultura to the Asian capital once widely called Peking, then to the constellation containing Canopus or the vitamin deficiency that causes scurvy.
It also tests important cultural and technical milestones: Bjarne Stroustrup’s C with Classes became C++, the coulomb is named for French physicist Charles-Augustin de Coulomb, and the Treaty of Paris ended the Crimean War in 1856. This broad category suits general-knowledge quizzes, classrooms, pub quizzes, and game nights that reward range more than specialization.

Good C trivia questions can cover any subject beginning with the letter C, including classical history, capitals, constellations, chemistry, computing, culture, medicine, and treaties.

Which programming language began as C with Classes?
