This is a medium-difficulty question that asks you to trace through a C++ code snippet and predict its output. It assesses your command of language semantics, operator precedence, and how the compiler handles common constructs—skills that matter in any technical interview, but especially in quantitative roles where reading and debugging existing codebases is routine.
To solve questions like this, you need to step through the code mentally, keeping track of variable scope, type conversions, and the order in which expressions evaluate. Interviewers use these problems to identify gaps in your working knowledge of C++, particularly around subtle behaviors that only emerge under careful inspection.
