Pointers, Arrays, and Dynamic Memory Allocation in C++

Flashcards on Pointers, Arrays, and Dynamic Memory Allocation in C++

Array

Stores elements in contiguous memory locations; the array name acts as a pointer to the first element.

Array Name

The name of the array acts as a constant pointer to the first element.

Accessing Array Elements with Pointers

Access array elements using pointer arithmetic, e.g., *(ptr + i).

Pointer out-of-bounds access

Accessing memory outside the bounds of the allocated array.

Dynamic Memory

Memory allocated during runtime, providing flexibility for unknown sizes; requires manual management.

Static Memory

Memory allocated at compile time with fixed size.

new operator

Allocates memory at runtime; size can be determined at runtime.

delete operator

Deallocates memory, preventing memory leaks.

Memory Leaks

Allocating memory with 'new' but not deallocating it with 'delete', leading to memory accumulation.

Dangling Pointers

Accessing memory after it has been freed, leading to undefined behavior.

Pointers and Arrays Task

Using pointers to find the max and min values in an array.
