Vigenère Cipher in C++: How It Works, and How to Break It
Three centuries as the indecipherable cipher, and 1.6 milliseconds to break. Working C++ for both directions, plus the attack that recovers the key.

How to succeed in the coding interviews?
The coding interview platform provided by several kinds of organizations is considered to be the best possible way of recruiting people who are the best fit for the organization. At the time of hiring the people for technical jobs, it is very much important to judge their technical skills and the first barrier to entry in this particular concept can be termed as the technical or coding interview.
Random Number Generation in C and C++ — rand(), the random Header, and Doing It Right
We measured rand() over 20 million samples. When modulo bias matters, when it does not, and why C++ random is both safer and faster.
Top Coding Competitions (Coding Comps) to Boost Your Career & Skills

Linked List in C: Complete Guide with Operations and Examples
A linked list in C chains heap-allocated nodes through pointers. Build one completely: all operations, complexity analysis and a tested full program.
Free Programming Abstractions Course – SEE
Stanford Engineering Everywhere (SEE) offers few computer science courses to students online and at no charge. Programming Abstractions course covers advanced programming topics such as recursion, algorithmic analysis, and data abstraction using the C++ programming language, which is similar to both C and Java.
Base64 Encoding and Decoding in C: Working Code and the Bugs to Avoid
The most copied base64 implementation in C has a heap over-read in its own example. Here is a correct one, checked against the RFC 4648 test vectors.
Kruskal’s Algorithm in C and C++ (Minimum Spanning Tree)
Kruskal’s algorithm builds a minimum spanning tree by sorting edges and rejecting cycles with union-find. Tested C, C++, and Python code included.
Porter’s Algorithm in C
Originally written in 1979 at Computer Laboratory, Cambridge (England), it was reprinted in 1997 in the book “Readings in Information Retrieval”. Initially it was written in BCPL language. Here is the list of implementations in other programming languages including C, Java and Pearl implementations done by author himself.
Algorithms in C
These algorithms are represented in terms of compact implementations in C so that readers can both understand their fundamental properties and implement them in real applications. The method of the analysis of algorithms is quite carefully designed. When appropriate, analytic results are described to explain why certain algorithms are preferred. In some cases, the practical algorithms’ relationship being discussed to purely theoretical results is also described.
