When to Use the Stack and Heap in C
In C , the primary memory allocation methods are the stack and the heap. Each has distinct characteristics that determine their suitability for specific memory management scenarios.
Stack Allocation
The stack is a Last-In-First-Out (LIFO) data structure that provides efficient and automatic memory management for local variables within a function.
