... allocation and deallocation:
extern and static variables are allocated in the fixed data memory of the program, auto variables
are allocated on the program stack, and register variables are allocated ... management resolves this problem by allocating and reallocating memory
dynamically. When the data set fills all available space in the array, we allocate a larger array
