Understanding C++ initialization and output in basic programs

This is an easy C++ question that tests whether you can trace through a short code snippet and predict its output accurately. It's the kind of question that appears early in technical interviews to establish a baseline understanding of language fundamentals and to ensure you can read code carefully under pressure.

To answer questions like this, you need to understand how variables are declared and initialized in C++, how the standard library handles output streams, and the order in which statements execute. The question rewards close attention to detail: a single character or whitespace difference can make your answer wrong. Interviewers use these questions to filter for candidates who are methodical and can spot subtle bugs before they ship.

• Variable declaration and initialization syntax
• Output stream formatting and std::cout
• Operator precedence and statement ordering
