Today I will cover why stack is faster than heap.

Similarly, when an item is removed from the stack, it is removed from the top of the stack in constant time, O(1).

The stack is typically allocated in the program’s memory space, which is typically much smaller and faster to access than the system’s memory space where the heap is located.

Below I have a few examples of how the stack and the heap work in C, and why it is faster than the heap in certain situations.

Caching can be used on both the stack and the heap, but it is more commonly used on the heap because the heap is used for dynamically allocated memory that is accessed globally.
