what is nanodegree program

Overview Functions are the basis for modular program design. To compile complex Ajax applications, you must have a deeper understanding of functions. Functions in JavaScript are different from other languages. Each function is maintained and run as an object. Through the properties of function objects, you can easily assign a function to a variable or pass the function as a parameter. Before proceeding, let

What is the relationship between utf8 and unicode encoding? What is the difference? UTF8 = Unicode Transformation Format -- 8 bit It is a Unicode transfer format. Converts a Unicode file to a BYTE Transfer Stream. UTF8 Stream Conversion

What is the Smss.exe process? Smss.exe (Session Manager subsystem), which is used to initialize system variables for the conversation management subsystem, the MS-DOS driver name resembles LPT1 and COM, calls the Win32 shell subsystem and runs in the Windows login process. This is a session management subsystem that

What is the memory leak in the program? We have written many programs with the keyword Free (). For example, I am in this post about some of the important operations of the list (Important operations on a Linked list) to delete the entire list of this function, the code snippet is as follows:struct node * deletel

Dynamic:The main is to postpone the determination of the data type by compile time to the runtime.This problem actually involves two concepts, runtime and polymorphism. Simply put, the run-time mechanism allows us to determine the class of an object until run time, and to invoke the class object to specify the method.Now, let me think about the dynamic language features of OC. The dynamic characteristics of OC are represented in three aspects: dynamic

Class concept: A class is a set of objects with the same attributes and services. It provides a unified abstract description for all objects belonging to this class, which includes two main parts: attribute and service. In an object-oriented programming language, a class is an independent program unit. It should have a class name and contain two main parts: attri

I am always talking about database learning. I remember a teacher told us to learn a course at a university.Programming LanguageIn addition to the database, and finally learn network programming, it is very easy for us to find a job after graduation. I have been learning databases for a while, but I always know nouns like ADO (ActiveX Data Object), Dao (Data Access Object), rdo (Remote Data Object), ODBC (Open Database Connectivity), oledb (ObjectLink

What is persistent connection and what is short connection?Post a classic post. After reading it, there should be no problem: Diversity of TCP/IP communication program design People who are new to TCP/IP communication design can quickly compile a communication

as cpu) orderly scheduling, the solution is multiplexing. multiplexing is dividedTime ReuseAndSpace Reuse. Space reuse: the memory is divided into several parts, each of which is put into a program. In this way, multiple programs exist in the memory at the same time. Time r

What is polymorphism. Concept: The same operation acts on different objects, can have different interpretations, produce different execution results, this is polymorphism. Simply put: the reference to the base class refers to the object of the subclass. Why use polymorphism? Reason: We know that encapsulation can hide implementation details, making code modular,

versions 1.0 through 1.4.5 is similar to both the BSD and ASF (APACHE) Public Licenses, which means it's free for use, even within implements cial products. From quartz 1.0 to 1.4.5, licensing is similar to BSD and ASF (APACHE) Public Licenses. It means that it can be used for free and even in commercial products.With the upcoming release of version 1.5.0, quartz is
