In compiler design, a handle is a substring of a string that can be reduced by a production rule in a given grammar. Specifically, it refers to a portion of the input that matches the right-hand side of a production and can be replaced by the corresponding non-terminal symbol on the left-hand side. Identifying handles is crucial for parsing techniques like bottom-up parsing, where the compiler systematically reduces the input string to the start symbol of the grammar. The correct identification of handles ensures the proper construction of the parse tree and the correct interpretation of the source code.

From Compiler Design by Chris Armen A handle of a string is a substring that matches the rhs of a production, and whose reduction to the lhs is one step along the reversal of a rightmost derivation. The process we went through can be viewed as "handle-pruning", where we're pruning the parse tree

No one knows and no one cares.
single possible output for a given input
Its not that the compiler can't initialize local variables; its that the compiler does not initialize local variables.This is by design and language specification. If you want to initialize local variables, you must explicitly do so.
