Answer:
The correct syntax (assuming WinForms) is
lblMessage.Text = "Welcome to fiji";
The given statement fails to follow the syntax of literal strings, which should be in quotation marks. (depending on the framework and programming language, the txt property may also be incorrect, as well as the missing semi-colon).
Answer:
1. Classes and objects
2. Inheritance
3. Polymorphism
4. Data hiding/ encapsulation
5. Interfaces.
Explanation:
Classes and objects depict the major component of the OOP (object oriented programming). It explains the object like a ball in a soccer game development.
The inheritance is like the subclass of the object. Data hiding is a stage in oop where the codes or data are hidden from another users.
In the polymorphism stage, the object is given the ability to change to a sub-object, while in the interface stage a function or method signature is defined without implementing it.
Answer: Public
Explanation:
A top level class can have a public, as top level cannot be private and protected because the modifier private is not allowed. As, top level is a class which is not a nested class. Interface of a access modifier is either public or no modifier. There are two types of access control modifier are top level - public and member level- private, protected.
Answer:
