The C language, created in the 70s, has its own logic and vocabulary. Through this test, you will be able to assess your knowledge and skills in C. The questions cover many notions, at a junior level. The areas covered are therefore:

  • Variables (types, scope, declaration)
  • Naming and accessing files
  • Preprocessor directives (define, macro, ifndef)
  • Functions (headers, call, declaration)
  • Loops
  • Pointers
  • Data structures (structures, tables)
This test consists of 20 questions randomly selected from a database of 45 questions in C.Discover all our interview questions and answers here
