What is the difference Stack and Heap?
Posted On: Jun 10, 2024
Our code takes up some space in the iOS. The size of this is sometimes fixed and sometimes it can change according to what the user will enter during the program. Basically, we have two different methods because of this difference: Stack and Heap.
A stack is used and automatically removes itself from memory after work is finished. But in Heap, the user could do it by writing manual code for deleting from memory.
| Stack: | Heap |
| • A stack is easy to use. | • Compared to Stack, it is quite slow. |
| • It’s kept in RAM on the computer. | • It creates memory problems if not used correctly. |
| • Created variables are automatically deleted when they exit the stack. | • Variables are used with pointers. |
| • It is quite fast compared to Heap. | • It is created at runtime. |
| • Constructed variables can be used without a pointer. |
