Programs in C & C++ with Example

Here is an example of Bubble sort in C++.  The example will perform bubble sort on a set of 10 integers. The example is a OO example . So everything is in a class called bubble. The class it self has following methods in it.

Finding Armstrong number is again a great exercise for students The exercise involves clever use of modulus operator to extract the digits and then using those digits to perform calculations.

In this Example I will demonstrate overloading a unary operator. The overloading is done in similar way as we did for binary operator. In this example I will be using a Vector Class. The operator we are going to over load is the unary "~" (tilde) operator. although you can use any unary overloadable operator. Method: In this example the overloaded operator will be the part of the class i.e. the over loaded definition will be a member function. (As we know overloading can be done using non member functions too). So the unary operator will not have any arguments in it. We will overload ~ operator so that it will reflect the vector so that its z component becomes x component and vice versa. So input vector will be 2i+3j+5k and its output vector will be 5i+3j+2k. although you can do anything you like. Code: # include < iostream > using namespace std ; class vector { int x , y , z ;      public : vector ( ) { x = y = z = 0 ; ...
