How long is the variable value accessible? - Answers

The accessibility of a variable's value depends on its scope and lifetime. Local variables are accessible only within the block or function where they are defined, while global variables can be accessed throughout the program. Additionally, the lifetime of a variable, which refers to how long it exists in memory, can vary based on whether it is allocated on the stack (temporary) or the heap (persistent until explicitly deallocated). Thus, the variable's accessibility is contingent upon its defined scope and memory management practices.
