[System Info] Heap Management - How Information about Allocations are Stored in the Heap

Lecture Description

Heap Management - How Information about Allocations are Stored in the Heap, Result of Freeing Memory Improperly, Actual Sizes of Heap Allocations - Nearest Power of 2, Management of Free Blocks on the Heap by Storing Addresses in the Blocks of Free Memory, Algorithms for Choosing Which Free Block to Allocate, How the Heap's Free List Can Be Updated When Memory is Freed, How Adjacent Free Blocks Are Combined To Avoid Fragmentation, Compacting the Heap By Using Handles, Stack Segment Layout, Allocation of Local Variables on the Stack by Decrementing the Stack Pointer, Activation Records and State of the Stack Pointer During Nested Function Calls, Assembly Code and the Code Segment, RAM, Registers, and the ALU, Example That Demonstrates How an Arithmetic Expression is Translated Into Register Operations

Course Description

Topics include: Advanced memory management features of C and C++; the differences between imperative and object-oriented paradigms; the functional paradigm (using LISP) and concurrent programming (using C and C++); brief survey of other modern languages such as Python, Objective C, and C#.

Prerequisites: Programming and problem solving at the Programming Abstractions level. Prospective students should know a reasonable amount of C++. You should be comfortable with arrays, pointers, references, classes, methods, dynamic memory allocation, recursion, linked lists, binary search trees, hashing, iterators, and function pointers. You should be able to write well-decomposed, easy-to-understand code, and understand the value that comes with good variable names, short function and method implementations, and thoughtful, articulate comments.
