long vs int

What this C++ integer-type knowledge question tests

This is a straightforward easy-difficulty question that probes your understanding of integer types and their behaviour in C++. It targets candidates who need to reason precisely about variable sizes, overflow, casting, and how the compiler interprets numeric literals and operations.

Questions in this area are common in technical screens because they reveal whether you've worked with low-level code or spent time reading and writing C++ carefully. The question asks you to trace through a code snippet and predict its output—a skill that matters when debugging performance-critical systems or catching subtle type-related bugs.

• Width and range of int vs. long on different platforms
• Integer overflow and wraparound behaviour
• Implicit and explicit type conversions
• Literal suffixes and type inference
