Data Types in C Program There is an extensive system that is used for declaring variables and functions in the C language. The variable types define how much space does it acquire in storage in bits. The types in C are as follows
Variables & Constants in C Program A variable is defined as the name given to store data in our C programs. Each variable inside a C language is of a specific type that defines the size of the memory of variables. Also, the range of values can also be stored inside the memory
Variables and Constants in C Program Constants are defined as the fixed values in the program that do not alter its execution. They are also called literals. In general, constants can be different types like integer, float, character, string, etc
Storage classes in C Program A storage class identifies the visibility of variables or functions in a C program. There are 4 different storage classes in a C language
Operators in C Program Operators are just symbols that inform the compiler to perform mathematical or logical functions in C language. There are different types of operators in C
C Program Loops - for,while,do-while After decision-making statements there comes the loops in C languages. In a loop, a block of code is executed sequentially a number of times mentioned in the statement. For example, the first statement will execute first, then second, and so on
Functions in C Program, different types of functions A function is a group of statements that helps in performing the task. If you have noticed in previous programs there is at least one function in every C program i.e. main()
Arrays in C Program, char array, int array The array is a type of data structure that can easily store a collection of elements of the same type. It is used to store a collection of data. In an array instead of declaring a separate variable for each number like number 1, number 2, you can declare only one array variable like numbers and then use it as numbers[0], numbers[1], etc

RxJava Tutorial RxJava Tutorial - RxJava is a Java based extension of ReactiveX. ReactiveX is a project which aims to provide reactive programming concept to various programming languages
RxJava - Environment Setup RxJava - Environment Setup - RxJava is a library for Java, so the very first requirement is to have JDK installed in your machine
RxJava’s Characteristics RxJava - Overview - RxJava is a Java based extension of ReactiveX. It provides implementation or ReactiveX project in Java. Following are the key characteristics of RxJava
RxJava - How Observable works RxJava - How Observable works - Observables represents the sources of data where as Observers (Subscribers) listen to them
RxJava - Single Observable RxJava - Single Observable - The Single class represents the single value response. Single observable can only emit either a single successful value or an error. It does not emit onComplete
RxJava - MayBe Observable RxJava - MayBe Observable - The MayBe class represents deferred response. MayBe observable can emit either a single successful value or no value
RxJava - Completable Observable RxJava - Completable Observable - The Completable class represents deferred response. Completable observable can either indicate a successful completion or error
RxJava - Using CompositeDisposable The CompositeDisposable class represents a container which can hold multiple disposable and offers O(1) complexity of adding and removing disposables
RxJava - Creating Operators RxJava - Creating Operators - Following are the operators which are used to create an Observable
RxJava - Transforming Operators RxJava - Transforming Operators - Following are the operators which are used to transform an item emitted from an Observable
RxJava - Filtering Operators RxJava - Filtering Operators - Following are the operators which are used to selectively emit item(s) from an Observable
RxJava - Combining Operators RxJava - Combining Operators - Following are the operators which are used to create a single Observable from multiple Observables
RxJava - Utility Operators RxJava - Utility Operators - Following are the operators which are often useful with Observables
RxJava - Conditional Operators RxJava - Conditional Operators - Following are the operators which evaluates one or multiple Observables or items emitted
RxJava - Mathematical Operators RxJava - Mathematical Operators - Following are the operators which operates on entire items emitted by an Observable
RxJava - Subjects RxJava - Subjects - As per the Reactive, a Subject can act as both Observable as well as Observer
RxJava - PublishSubject RxJava - PublishSubject - PublishSubject emits items to currently subscribed Observers and terminal events to current or late Observers
RxJava - BehaviorSubject RxJava - BehaviorSubject - BehaviorSubject emits the most recent item it has observed and then all subsequent observed items to each subscribed Observer
RxJava - AsyncSubject RxJava - AsyncSubject - AsyncSubject emits the only last value followed by a completion event or the received error to Observers
RxJava - ReplaySubject RxJava - ReplaySubject - ReplaySubject replays events/items to current and late Observers
RxJava - Schedulers RxJava - Schedulers - Schedulers are used in multi-threading environment to work with Observable operators
RxJava - Trampoline Scheduler RxJava - Trampoline Scheduler - Schedulers.trampoline() method creates and returns a Scheduler that queues work on the current thread to be executed after the current work completes
RxJava - NewThread Scheduler RxJava - NewThread Scheduler - Schedulers.newThread() method creates and returns a Scheduler that creates a new Thread for each unit of work
RxJava - Computation Scheduler RxJava - Computation Scheduler - Schedulers.computation() method creates and returns a Scheduler intended for computational work. Count of threads to be scheduled depends upon the CPUs present
RxJava - IO Scheduler RxJava - IO Scheduler - Schedulers.io() method creates and returns a Scheduler intended for IO-bound work. Thread pool may extend as needed. Best for I/O intensive operations
RxJava - From Scheduler RxJava - From Scheduler - Schedulers.from(Executor) method converts an Executor into a new Scheduler instance
RxJava - Buffering RxJava - Buffering - Buffering operator allows to gather items emitted by an Observable into a list or bundles and emit those bundles instead of items
