Presented by Ted Higgins, SQL Server DBA C Programming - Pointers

This presentation will define and illustrate the power of pointers using the C programming language. Definition: I’ll demonstrate how pointers are created, initialized and used in a program. Dynamic Memory Allocation: I’ll demonstrate this technique in a C program. Power to the Pointer: I’ll describe and illustrate some simple data structures where pointers are key functional components. Finally I’ll describe and illustrate how memory leaks are generated and the code that creates these sometimes hard-to-find bugs. Introduction
