Where in memory are local variables usually placed during program execution?

Local variables during program execution are usually placed in stack memory. The stack is a memory area that is managed automatically: when entering a function, memory is allocated for local variables, and when exiting the function, this memory is freed.

The stack operates on a LIFO (last in, first out) principle, which ensures fast access to local variables and control over their lifetime. Unlike the heap, where objects with dynamic lifetimes are stored, the stack is limited in size and intended for short-term data storage.
