Which of the following is a key difference between static and dynamic array initialization?
Understand the Problem
The question asks us to identify the key difference between static and dynamic array initialization. We need to consider when and how memory is allocated for each type of array, and whether their sizes can be changed after initialization. Static arrays have fixed sizes determined at compile time, while dynamic arrays can have their sizes determined at runtime.
Answer
Static arrays require a size to be defined at compile time, whereas dynamic arrays can have their size defined at runtime.
The key difference between static and dynamic arrays is that the size of a static array must be known at compile time, while the size of a dynamic array can be set at runtime.
Answer for screen readers
The key difference between static and dynamic arrays is that the size of a static array must be known at compile time, while the size of a dynamic array can be set at runtime.
More Information
Static arrays are allocated on the stack, while dynamic arrays are allocated on the heap. Dynamic arrays require manual memory management.
Tips
Confusing the terms compile time and run time can lead to errors about static and dynamic arrays.
