Vigenere cipher

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.

Quadratic Formula and Quadratic Equation

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)

hello_world_cpp

C++ “Hello World” Program

Typically, the best way to learn programming is by writing code. The first program beginners write is “Hello, World!” which is often used to illustrate the syntax of a programming language. You can take a look at the list of Hello World Programs in 300 Programming Languages to see how “Hello, World!” looks like in different programming languages.

Add Time Using Structures

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.

C++ Inheritance

C++ program to demonstrate Inheritance

This is a simple C++ Program to demonstrate Inheritance. Simpler methods in the classes have been changed to inline code to shorten the file considerably. In a practical programming situation, methods that are this short should be programmed inline since the actual code to return a simple value is shorter than the code required to send a message to a non-inline method.

IP-Configuration

Change IP configuration using C++

This sample illustrates how to programmatically change an IP address for a specific network adapter on your machine. This program also demonstrates how to retrieve existing network adapter IP configuration information using Win32 APIs.
