Rock, Paper, Scissors Game in C++

This is a simple C++ program to demonstrate rock, paper, scissors game. In this game, players have to choose one of the three options to beat the opponent or the computer itself. The C++ code generates a random choice by creating a character to indicate that option. Options are: r is for ‘rock’, p is for ‘paper’, and s is for ‘scissors’.

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.

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)

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.
