What Is Static Array And Dynamic Array In C?

What are static and dynamic arrays in C? Static arrays are arrays whose memory allocation occurs during compile time, and this memory is typically located on the program’s stack. In contrast, dynamic arrays allocate memory during runtime, and this memory is typically sourced from the program’s heap. To illustrate, consider a static integer array like the one below, which preallocates memory before program execution:

c
int arr[] = {1, 3, 4};

This code snippet showcases a static array with fixed memory assignment at compile time. The concept of static and dynamic arrays is fundamental in C programming, offering flexibility in memory management to suit different program requirements.

Is Array Static Or Dynamic In C?

Is an array static or dynamic in C? In C, arrays are considered static in nature, meaning their size must be known at compile time, and it is impossible to alter the array’s size after it has been declared. This characteristic of C arrays limits their flexibility when it comes to resizing or modifying them after initialization, making it crucial to define their size accurately during coding. This fundamental aspect of C arrays was valid as of January 11, 2023.

What Is A Static Array In C?

A static array in C maintains its existence throughout the entire duration of a program’s execution. This means that even when a static array is declared within a specific function, it doesn’t get destroyed when the function’s execution ends. Instead, the data stored in a static array persists beyond the function’s scope and remains accessible the next time that same function is invoked. This enduring quality distinguishes static arrays from other types of arrays in C and makes them particularly useful for retaining data across multiple function calls within a program.

Static Arrays vs. Dynamic Arrays

Static Array: In this type of array, memory is allocated at compile time having a fixed size of it. We cannot alter or update the size of this array. Dynamic Array: In this type of array, memory is allocated at run time but not having a fixed size.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. This is static integer array i.e. fixed memory assigned before runtime int arr[] = { 1, 3, 4 };Array in C is static in nature, so its size should be known at compile time and we can’t change the size of the array after its declaration.
