#Competitive Programming C Code Screen

Will This C++ Code Compile? Day 37 / 365✅ This question looks calm, clean, and completely harmless. No complex syntax. No templates. No STL tricks. Just a small class, a constructor, and one extra line that most people won’t even think twice about. And that’s exactly why it works so well as a filter question. If you’re learning C++, this is the kind of code that decides whether you understand the language or you’re just memorizing patterns. At first glance, everything feels valid. A class is defined. A constructor exists. The program creates an object. Then another object is created using the first one. Many learners subconsciously assume, “Of course it compiles. This is basic object creation.” That assumption is where the trap lives. C++ is very strict about object copying. Whenever you create a new object from an existing one, the compiler looks for a copy constructor. If it’s available, it uses it. If it’s not, it tries to generate one automatically. And if you explicitly tell the compiler not to allow copying, it listens. That single deleted copy constructor line silently changes everything. This question tests whether you actually understand what happens behind the scenes when objects are created, not just what you see on the screen. It’s not about output. It’s not about syntax errors. It’s about the rules of the language and how seriously the compiler enforces them. Many people confuse runtime errors with compile-time errors here. Others think the default constructor will somehow save the situation. It won’t. C++ doesn’t guess. It doesn’t forgive. It follows the rules exactly as written. If you’ve ever wondered why interviewers love asking “Will this code compile?”, this is the reason. Because these questions reveal whether you understand constructors, deleted functions, object lifetimes, and compiler behavior as a system — not as isolated topics. If this question felt confusing, that’s actually a good sign. Confusion means you’ve hit a real concept boundary, not just a memory gap. Once you truly understand this, a lot of C++ behavior suddenly starts making sense: move semantics, rule of three, rule of five, and why modern C++ is designed the
