/**
 * @brief This file contains the implementation of a simple class 'demo' that demonstrates
 * the usage of input and output operations on private member variables.
 *
 * The 'demo' class has two private integer member variables 'a' and 'b'. It provides
 * two public member functions: 'input' to accept user input and store it in the private
 * member variables, and 'show' to display the values of the private member variables.
 *
 * The main function creates an instance of the 'demo' class, calls the 'input' and 'show'
 * methods, and then returns 0 to indicate successful program termination.
