SKILL BENCHMARK
C Programming Proficiency (Advanced Level)
- 20m
- 20 questions
The C Programming Proficiency benchmark will measure your ability to perform various file operations and recognize the steps for compiling a C program, including creating macros with preprocessor directives, controlling conditional compilation, and using pragmas to alter compiler settings. You will be assessed on your skills, including working with C strings using character arrays, library functions, and header files; understanding and performing type conversions; and using command-line arguments in C programs. A learner who scores high on this benchmark demonstrates that they have the necessary skills to implement file handling, perform string operations, and create macros.
