LRU and FIFO L1 Cache Implementation using C

LRU and FIFO L1 Cache Implementation using C

This is a C program to demonstrate cache mechanism by simulating a cache in C. The source code can run in any C Compiler with minor modifications if required. It can run on real memory traces as input to your cache simulator. We have implemented two cache replacement policies i.e. least recently used (LRU) and First-in first-out (FIFO) replacement policies.

C Algorithms Library

This article is about a collection of common Computer Science algorithms which may be used in C projects. The C Programming Language has a much smaller Standard Library as compared to other more modern programming languages such as Java or Python. The library provides a basic set of mathematical functions, string manipulation, type conversions, and file and console-based I/O.

C Implementation of Base64 Encoding and Decoding

Base64 encoding and decoding schemes are commonly used to encode binary data. Normally this is required when textual data needs to be transferred over the network or similar media and make sure that data is transferred without any modification. Base64 is commonly used in a number of applications, including email via MIME, and storing complex data in XML. This is a very simple implementation of base64 encoding and decoding in C programming language. There are number of C libraries available for encoding and decoding as well i.e. libb64, OpenSSL Base64, Apple’s Implementations, arduino-base64 etc.

JavaScript – Difference Between [] and {}

In JavaScript, we use {} braces for creating an empty object. We use [] brackets for creating an empty array. I find the Developer console in Mozilla Firefox or Google Chrome more convenient to print out any object and study the details.

C++ Wave File Writer from Text File

This C++ program is capable of turning a text file describing the notes of a piece of music into an audio file (.wav). The program reads the contents of the input file i.e. input.txt, constructs Song, Voice and Note objects describing the notes in the file, and call...

Vigenere Encryption and Decryption in C++

The Vigenere cipher is a method of encrypting or decrypting alphabetic text by using a series of interwoven Caesar ciphers (Caesar Shift), based on the letters of a keyword. In cryptography, Caesar shift is one of the simplest known encryption techniques. It employs a form of polyalphabetic substitution, which is using multiple substitution alphabets.

C++ Program to solve the Quadratic Equation

This program will solve quadratic equations. It accepts coefficients of a quadratic equation from the user i.e. a, b and c and displays the roots. To compile the program name it quadratic_solver.cpp then type g++ -o quadratic_solver quadratic_solver.cpp You may need to use math.h like this: #include if you are using windows C++ programming software. (I tried it without the math.h and got an “undeclared identifier” error)

Kruskal’s Algorithm Implementation in C

This is the implementation of Kruskal’s Algorithm in C Programming Language. This algorithm is directly based on the generic MST (Minimum Spanning Tree) algorithm. Kruskal’s algorithm is a greedy algorithm in graph theory that finds a minimum spanning tree for a connected weighted graph. It finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized.

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.

Add time using structures in C++

This is a C++ implementation of adding time using structures. A structure is a convenient tool for handling a group of logically related data items. Structure help to organize complex data is a more meaningful way. It is powerful concept that we may after need to use in our program Design.
