Pointer: Pointer is a special type of variable to store the address of the memory location, which can be accessed later. If an asterisk “” operator is present before the variable, then that variable is referred as pointer variable. It is also called as dereferencing or indirection operator. Pointer is just a type of variable that stores the addresses of other variables. Using pointers, the address of a variable can be accessed and the data stored in that variable can be retrieved. Syntax of pointer variable declaration: <variable-type> <variable-name>; Usage of pointers to structures: The usage of pointers to structure is same as declaring a pointer variable.

Program Plan Intro

Pointer:

Pointer is a special type of variable to store the address of the memory location, which can be accessed later.

If an asterisk “” operator is present before the variable, then that variable is referred as pointer variable.

It is also called as dereferencing or indirection operator.

Pointer is just a type of variable that stores the addresses of other variables.

Using pointers, the address of a variable can be accessed and the data stored in that variable can be retrieved.

Syntax of pointer variable declaration:

<variable-type> <variable-name>;

Usage of pointers to structures:

The usage of pointers to structure is same as declaring a pointer variable.

Objective you will: 1. Implement a Binary Search Tree (BST) from scratch, including the Big Five (Rule of Five) 2. Implement the TreeSort algorithm using a in-order traversal to store sorted elements in a vector. 3. Compare the performance of TreeSort with C++'s std::sort on large datasets. Part 1: Understanding TreeSort How TreeSort Works TreeSort is a comparison-based sorting algorithm that leverages a Binary Search Tree (BST): 1. Insert all elements into a BST (logically sorting them). 2. Traverse the BST in-order to extract elements in sorted order. 3. Store the sorted elements in a vector.
