Binding Behavior

What this C++ variable scoping question tests

This easy question probes your understanding of name binding and variable shadowing in C++. It is a common warm-up in technical interviews to establish baseline fluency with scope rules before moving to harder problems.

The question rewards careful reading of scope boundaries and the ability to distinguish between local, block-local, and global variable declarations. You need to trace which declaration is active at each point in the code, and understand how the scope-resolution operator (::) lets you bypass shadowing to access names in outer scopes.
