LRU and FIFO L1 Cache Implementation using C

Posted by M. Saqib | Jan 4, 2021 | C Programming Source Code |

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.

Vigenere Encryption and Decryption in C++

Posted by M. Saqib | Jan 1, 2021 | C++ Source Code: C++ Programming Concepts |

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.
