Local variables are declared inside the function blocks whereas Global variables are the type of variables that are declared outside every function of the program. Local variables are stored on the stack, with their memory allocated and deallocated as functions are called and return.
21 mar 2024 · Local Variables: Local variables are declared within a specific block of code, such as within a function or a loop. They are only accessible within the block in which they are declared. Once the block of code in which they are declared exits, the memory allocated to these variables is released, and they are no longer accessible.
