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++ Inheritance
C++ Source Code Examples – Classes, Inheritance & Polymorphism

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.
