Playfair Cipher Algorithm Program in C/C++

In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, “cipher” is synonymous…

LFU Page Replacement Algorithm Program in C/C++

In a computer operating system that uses paging for virtual memory management, page replacement algorithms decide which memory pages to page out, sometimes called swap out, or write to disk when a page of memory needs to be allocated. Page replacement happens when a requested page is not in memory (page…
