Which aspect of programming languages deals with memory management?

In programming languages, memory management is primarily concerned with how variables are stored, accessed, and managed in memory during the execution of a program. Variable scope plays a crucial role in this aspect because it defines the regions in code where variables can be accessed and manipulated. Scope determines the lifespan of a variable, which directly influences memory allocation.

When a variable is declared, it can occupy memory locations that may vary in their accessibility depending on the defined scope (e.g., local, global). The broader the scope, the longer the variable remains in memory, and it can lead to inefficient memory use if not managed properly. Conversely, variables that are limited to a narrower scope can be allocated and deallocated efficiently, borrowing memory only when necessary.

Understanding variable scope is integral to effective memory management, as it helps prevent issues like memory leaks or inadvertent access to variables that should be out of reach, leading to cleaner and safer code. This clarity in the lifecycle and visibility of variables makes variable scope essential to memory management strategies in programming languages.
