Computer Science – Arrays | e-Consult

A static array is an array whose size is fixed at the time it is created. The amount of memory allocated for the array remains constant throughout the program's execution. A dynamic array, on the other hand, can change its size during the program's execution. It automatically allocates more memory as needed.

Static Array:

• Advantages: Faster access because the size is known in advance. Less memory overhead.
• Disadvantages: Cannot accommodate more elements than its initial size. Wasted memory if the array is larger than needed.

Dynamic Array:

• Advantages: Can grow as needed, avoiding the problem of fixed size limitations. More efficient use of memory (only allocates what's required).
• Disadvantages: Potentially slower access because the array might need to be resized (copying elements to a new, larger memory location). More memory overhead due to the dynamic allocation mechanism.
