Knowledge of Basic Bit level Operations

Good in applying raw Pointers Arithmatic in C/C++

Description

This course is designed for System Programmers, Kernel developers, Embedded programmers Or anyone who need to work at low-level memory manipulation ( at bit level ).This is an Advance level Course in bit-programming, so it is assumed that the student is already familiar with basic bit-wise operators in C/C++.In this course we will implement a bitmap library that is endian-ness independent. A bitmap is nothing but an array of bits. We will be going to implement some advanced operations on bitmaps.We will also be introduced to the concept of Masks and WildCards and how to use them.We ended this course by Implementing some real-world problems and data structures that conceptually works at the bit level. For example, Bloom Filters, Checksum, File-Compression Or Cryptographic algorithms to name a few.The End Product of this course is a bitmap library which will be needed in sequel course which we will be dedicated to implementing a Advance Data structures extensively used in Networking - Routing Tables and Access Control Lists. We will then see how to implement more sophisticated Networking utilities such as packet sniffers Or Packet Filters OR integrate our Libraries within Linux Networking stack.So, be ready to write lots of bit-level code and see how things works at bit level.
