Enterprises and businesses preparing to develop small programs must first find out what kind of small programs they need, and then develop them. So, what are the types of applets? Let's have a look ~ 1. E-commerce applet E-commerce applet accounts for the largest proportion in all kinds of applets, among which small programs in sub-sectors such as fresh e-commerce, maternal and child e-commerce and fashion e-commerce account for the largest proportion. E-commerce applet can not only display goods, place orders, pay and other functions, but also track express delivery, which is very convenient to use. 2. Booking applet With the development of the Internet, it seems to have become a habit to book hotels, air tickets, tickets and meals online before traveling. Booking tickets online is not only convenient and fast, but sometimes you can enjoy a certain discount. For enterprises and merchants engaged in hotel, ticketing and catering industries, if they have their own small programs, they can let users make reservations through their own platforms, which will not only help improve the user experience, but also save the cost of cooperation with third-party booking platforms. In addition, applets can also be used with their official accounts in official website and WeChat to get more traffic. 3. Regional service applet Regional platform class is also a type of applet, such as housekeeping service, beauty salon, cleaning service and so on. With the improvement of people's living standards, more and more people like to be served, so the regional service applet has also developed rapidly. For enterprises and merchants engaged in regional services, if they have their own applets, they can let their shops and enterprises radiate to people within 5 kilometers around them through the functions of nearby applets, thus bringing a certain amount of traffic. In addition, when choosing related services, it is usually more inclined to choose the nearest service provider. Therefore, for enterprises and businesses engaged in regional service industries, applets are definitely a very good channel for promotion and customer drainage. In fact, there are many kinds of small programs, besides the above, there are gyms, education, games, tools and so on. Therefore, before doing small programs, enterprises and businesses must first find out what kind of small programs they need and what functions they need, so that small programs can be developed smoothly. What language is used to write software?

The languages in which the software is written are

AI language

C language is a process-oriented abstract general programming language, which is widely used in the underlying development. C language has the characteristics of high efficiency, flexibility, rich functions, strong expressive force and high portability, and is favored in programming. C language compilers are ubiquitous in various operating systems, such as MicrosoftWindows, macOS, Linux, Unix and so on. The design of C language influenced many later programming languages, such as C++, Objective-C, Java, C# and so on.

Second, C++

C++ is an object-oriented computer programming language, which was invented and realized by Dr. Benjani Strastrup of ATT Bell Laboratories in the early 1980s. It was originally called "CwithClasses" (C language containing classes). It is a general programming language that checks static data types and supports various programming paradigms, and supports various programming styles such as procedural programming, data abstraction, object-oriented programming and generic programming. C++ is the inheritance of C language, which further expands and perfects C language and becomes an object-oriented programming language.

Third, PHP

PHP (MBTH: PHP: Hypertext Preprocessor, Chinese name: Hypertext Preprocessor) is a universal open source scripting language. Grammar absorbs the characteristics of C language, Java and Perl, which is beneficial to learning and widely used, mainly in the field of Web development. The unique syntax of PHP is a mixture of C, Java, Perl and PHP's own syntax. It can execute dynamic web pages faster than CGI or Perl. Compared with other programming languages, dynamic pages made by PHP embed programs into HTML (an application under standard generalized markup language) documents for execution, and the execution efficiency is much higher than CGI which completely generates HTML tags. PHP can also execute compiled code, which can realize encryption and optimize code operation, making the code run faster.

Fourth, JAVA

Java is a widely used computer programming language, which has the characteristics of cross-platform, object-oriented and generic programming, and is widely used in enterprise Web application development and mobile application development.

Verb (abbreviation for verb) computer programming language

Python is a computer programming language, which was created by Guido Van Rossum. The first edition was published in 199 1, which can be regarded as an improvement of LISP. Python's design philosophy emphasizes readability and concise syntax of code. Compared with C++ or Java, Python enables developers to express ideas with less code.

What are the main programming languages in computers?

Machine language, the lowest language, consists of binary codes and is the earliest programming language; Assembly language, using mnemonics and address symbols instead of binary codes, is easier to write; High-level languages, compared with assembly languages, are one step higher and closer to natural languages, such as C language, Pascal, Java and C#. Computer language refers to the language used for communication between people and computers. Computer language is a medium for transmitting information between people and computers. The biggest feature of a computer system is to convey instructions to the machine through a language. In order to make the electronic computer do all kinds of work, it is necessary to have a set of numbers, characters and grammar plans when writing computer programs. These characters and grammar rules form various instructions (or sentences) of the computer. These are languages acceptable to computers.

What are the softwares for developing software? What programming language is it usually written in?

Java development tools

SunJavaStudio is the latest commercial full-featured JavaIDE released by Sun Company, which supports Solaris, Linux and Windows platforms, and is suitable for enterprise developers who create and deploy two-tier JavaWeb applications and n-tier J2EE applications.

Net software development tool

1、MicrosoftVisualStudio

VisualStudio is a set of development tools for generating ASPNETWeb applications, XMLWebservices, desktop applications and mobile applications. VisualBasic, VisualC# and VisualC++ all use the same integrated development environment (IDE), so they can enjoy tools and easily create mixed language solutions. About common software development tools.

Common software development languages: JAVA,. Net, C/C++/C#, JSP, ASP, PHP and other languages. Among them PHP, Java and. NET has become a necessary skill for programmers in the next five years, and all three languages have a place in the field of Web development. PHP is the scripting language of the network; Java is powerful and suitable for enterprise programming languages. C# combines the advantages of several languages.

Can I develop an app in C language?

Yes, C language is originally a program for developing software.

C language is more suitable for operating system-related development, such as drivers and embedded systems. It's too difficult to develop mobile App in C language. It seems that few people do it.

Unique characteristics

C language is a procedural language with the functions of structured programming, variable scope and recursion.

The parameters passed by C language are all passbyvalue, and pointers can also be passed.

Different variable types can be combined with structures.

There are only 32 reservedkeywords, which makes the naming of variables and functions more flexible.

Some variable types can be converted, such as integer and character variables.

Through pointers, C language can easily control the memory at a low level.

Preprocessor makes the compilation of C language more flexible.
