C++ class program example: In our code we create a class named programming with one variable and two functions. In main we create an object of class and call the functions using it.
#include<iostream> using namespace std; class programming { private: int variable; public: void input_value() { cout << "In function input_value, Enter an integer\n"; cin >> variable; } void output_value() { cout << "Variable entered is "; cout << variable << "\n"; } }; main() { programming object; object.input_value(); object.output_value(); //object.variable; Will produce an error because variable is private return 0; }
