- 1ARRAY-An array stores a fixed-size sequential collection of elements of the same type
-All arrays consist of contiguous memory locations
-the first space in the index is zero 0 - 2Declaring an Arraydatatype[] arrayName;
ex: int [] numberOfPens
You can assign values during the declaration like
datatype[] name{ }
ex: string[]colors{"red","blue",green"}; - 3Initializing an ARRAYdatatype[] name = new datatype[10];
you can assign through initialization
ex: int[]cars=new int [3] {4,3,10};
You can omit the size of an array
int[]cars = new int[] {4,5,10}; - 4METHODSMethods are VERBS
A method is a group of statements that together perform a task. Every C# program has at least one class with a method named Main. - 5Method format(Parameter List)
{
Method Body
}
ex: public int grades ( A, B, C,D) - 64 Pillars of OOP1.) Abstraction
2.) Encapsulation
3.) Inheritance
4.) Polymorphism - 7AbstractionExpose relevant functions and hides irrelevant, abstract complexity, a wrapper, private vs public properties.
- 8InheritanceThe ability of creating a new class
from an existing class.
The base class has properties and methods
that will be inherited by the sub class and it can have additional properties or methods. - 9Encapsulationis defined 'as the process of enclosing one or more items within a physical or logical package'. Encapsulation, in object oriented programming methodology, prevents access to implementation details.
access specifiers: public, private, protected etc. - 10PolymorphismPolymorphism refers to the ability
to take into different forms or stages.A subclass can define
its own unique behavior and still share the same functionalities or behavior of its
parent/base class. - 11Interface
