Programming tips and notes

Object array can be made in C++ by the following syntax:  Class name variable name[size] ={object1,object 2,....,objectn}; Example:

Constructors: Member function whose name is same as class. It doesn't return any value not even null. It is called at the time of the creation of the object. It is called explicitly. It is always public. Types of constructors: Default Parameter Copy     Default constructor : It doesn't take any argument it is used when we want to initialize data members of an object.    Parameterized constructor : This type of constructor accept the parameter and the value is used to initialize data members of the object.    Copy constructor : This type of constructor takes object reference as a parameter and use the passing reference to assign value to that object. C++ Constructor Example : Code: Output: Sum is :0 Sum is :6 Sum is :6 Java Constructor Example: Code: Output: Sum is :0 Sum is :6 Sum is :6

Code: Output: 36HoursMinutes1Seconds2

So the app starts with a registration menu and an option to login if you are an old user and redirect you to the login screen and if the login is successful it redirects to welcome screen with log out button. Backend: MainActivity.java(Registration menu): login.java: welcome.java Frontend: activity_main.xml: activity_login.xml: activity_welcome.xml: So that is how the app integrates and comes out as ->

This is my first app made which reverse any input a user give. Software Required: 1.
