What is a dynamic array? A dynamic array is similar to an array, but with the difference that its size can be dynamically modified at runtime. Don’t need to specify how much large an array beforehand. The elements of an array occupy a contiguous block of memory, and once created, its size cannot be changed.
How do you use a dynamic array in Python?
- Allocate a new array list2 with a larger capacity.
- Set list2[i] = list1[i], for i = 0,1…. n-1, where n is the current number of the item.
- Set list1=list2, as now list2 is referencing our new list.
- And then, just insert (append) new item to our list (list1).

What is static array in C++?
Static arrays are allocated memory at compile time and the memory is allocated on the stack. Whereas, the dynamic arrays are allocated memory at the runtime and the memory is allocated from heap. int arr[] = { 1, 3, 4 }; // static integer array. int* arr = new int[3]; // dynamic integer array.
What is static array in Java?
An array that is declared with the static keyword is known as static array. It allocates memory at compile-time whose size is fixed. We cannot alter the static array. If we want an array to be sized based on input from the user, then we cannot use static arrays.
