Your question is C Concepts and Pointers. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about your experience with C concepts and pointers.
Discuss how pointers represent addresses, how dereferencing and pointer arithmetic work, and how you have used them in real C code. Include one concrete example involving arrays, structures, dynamic allocation, or a function argument, and explain how you would avoid or debug a null, dangling, or leaked pointer.
The interviewer is checking both practical experience and understanding of C memory behavior. Keep the discussion focused on standard C and manual memory management.
