C Programming Language Quiz
The article discusses a quiz focused on the quirks of the C programming language. It highlights various aspects of pointer comparison and integer constant types, emphasizing the potential for undefined behavior. Additionally, it addresses the implications of these quirks on portability and function calls across different platforms.
- ▪The quiz is designed for fun and educational purposes, covering various aspects of the C programming language.
- ▪Accessing an object of one type through a pointer of another incompatible type can lead to undefined behavior.
- ▪The type of an integer constant may differ based on whether it is represented in decimal or hexadecimal format, which can affect function calls and arithmetic expressions.

C Programming Language Quiz This quiz is about quirks of the programming language C and intended for fun and educational purpose. The one or the other question is more academic, i.e., it should make you think ;-) Unless otherwise stated, the questions and corresponding answers are independent of a specific version of the C standard. Thus the answers are the same considering C89 up to and including C17 and probably future releases. If two pointers p and q of the same type point to the same address, then p == q must evaluate to true. Yes No Short answer: Comparing two pointers which are derived from two different objects which are not part of the same aggregate or union object invokes undefined behavior. Have a look at this post for a detailed discussion.
