Got Tricked… or Still Guessing? Day 38 / 365 This is C language, not C++. And C does NOT care about your expectations. If you think every program has a “fixed output”, you’re already wrong. This question exists to expose one word that scares beginners and embarrasses confident learners: Undefined Behavior. Same code. Same compiler. Different machine. Different optimization. Different output. Or maybe no output at all. Most people try to calculate the result like math. That’s the trap. C is close to hardware. If you break its rules, it doesn’t warn you politely — it lets chaos happen. This reel is testing whether you actually understand: – sequence points – expression evaluation order – side effects – why some C programs are not predictable If you answered with a number instantly, slow down. That confidence will fail you in exams and interviews. This exact type of question shows up in: C MCQs Compiler-based tests College exams Interview screening rounds And it’s used to filter out people who guess from people who know. No syntax error here. No runtime error message. Just logic punishment. 🎯 Rule: Comment the correct option only. No explanations. No edits. Let the song play. Let the confusion hit. If this one messed with your head, follow — because the next one is worse. More C traps incoming. Same energy. Harder logic. 🎵 Song: Hotel Room #clang #cprogramming #codingchallenge #undefinedbehavior #365daysofcode

Day 37/365 This is a classic C++ interview MCQ that checks whether you actually understand if–else condition flow, not just syntax. No tricks, no hidden lines—just pure logic. The program starts with an amount of 3500 and a discount initialized to 0. The conditions are evaluated top to bottom, and only the first true condition runs. That’s it. No rechecking. No multiple matches. Since the amount is not greater than 5000, the first if block is skipped. The next condition checks whether the amount is greater than or equal to 3000. This condition is true, so the discount is set to 10%. The else block is completely ignored. After that, the discount is applied using this line: amount -= (amount * discount) / 100; This means 10% of 3500 is calculated and subtracted from the original amount. The final value is then printed using cout. This type of question is extremely common in: C++ placement rounds First-round coding interviews Output-based MCQs College exams Most wrong answers happen because people: Ignore condition order Assume multiple conditions execute Forget how integer percentage calculation works If you can’t solve this mentally, you’ll struggle in timed interviews. Simple as that. Practice predicting output before running code. That’s how you actually get better. Comment your answer. Save this for revision.

Daily C++ Dose – Day 63 🧠💻 This C++ question tests your understanding of the dangling else problem. Many programmers think the else belongs to the first if, but in C++ an else always attaches to the nearest unmatched if. Here, colors = 3, so the first condition if (colors == 3) is true. Then the program checks if (colors > 5) which is false, so the else attached to this second if runs. As a result, the output becomes "Perfect Holi" 🎨 Small syntax structures like this can completely change program logic, which is why understanding control flow is extremely important in C++.

Day 36/365 of mastering C programming interview questions 🚀 Let’s check your logic with a classic C if-else MCQ that looks easy but actually tests your fundamentals. In this question, a bill value is already defined and a discount is applied using an if–else if–else ladder. The output depends entirely on which condition becomes true first. Many students calculate all discounts in their head but forget that C executes only one block from the ladder. This type of question is extremely common in C language interviews, college exams, and MCQ-based tests. It checks your understanding of conditional statements, percentage calculation, and variable modification before printing. If you understand: how if-else ladders work in C how float values affect calculations how the final value is stored and printed then you can solve this instantly without guessing. These questions are not about memorizing syntax. They are about thinking like the compiler. That’s why practicing small logic-based MCQs daily builds strong confidence for interviews and exams. 👉 Drop your answer in the comments 👉 Save this post for revision 👉 Share it with someone learning C 👉 Follow for daily C, C++, and programming interview questions One question every day is enough to level up your logic. #TCProgramming #TCLanguage #TCInterviewQuestions #TCIfElse #TProgrammingMCQs TCodingInterview TPlacementPrep TLearnC TCodingLogic TComputerScience TCodeDaily

Day 47/365 🚀 C Tricky Question 🧠 What will be the output? 😏 This question may look extremely simple, but it targets one of the most important concepts in C programming that frequently appears in exams, interviews, and coding tests — the post-increment operator. In C, understanding how increment operators work is absolutely essential. Many beginners assume that x++ immediately increases the value before it is used, but that’s not how it actually behaves. The subtle difference between pre-increment (++x) and post-increment (x++) is a classic source of confusion. This type of question is very common in C interview questions because it tests your understanding of operator behavior, expression evaluation, and how values are passed to functions like printf. Small details like these often decide whether your answer is correct or not. If you are learning C programming, preparing for technical interviews, or strengthening your programming fundamentals, mastering increment operators is critical. These concepts are not just theoretical — they directly affect real-world code behavior. Take a careful look at the code. Think about when the value of x is used, when it is incremented, and what exactly gets printed. This is where many learners make mistakes. Can you solve it without running the program? 🔥 Drop your answer below 👇 Let’s see how strong your C fundamentals really are 💡

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
