c. main applications java php

First , Let's popularize the basic knowledge of programming language first . Develop programs in any programming language , It's all about getting the computer to do the work , For example, writing an article , Download one MP3 etc. , Computers do the work CPU Know only the instructions of the machine , therefore , Although different programming languages vary greatly , In the end “ translate ” become CPU Machine instructions that can be executed . In theory, almost any language can do anything , But the main thing is different .


C、C++、Java、PHP、Python What are they used to develop ?

java Often follow “ Enterprises ” Connect , Because it has some good language features , And a rich framework , It's most popular in enterprise applications , You can always hear about J2EE,JSP,Hibernate Discussion of things like that . meanwhile , java There is also a place in the mobile phone field , Before universal intelligence , A lot of mobile phones just support java Use as a selling point , And after the explosion of smartphones ,java Mobile home has become android, As Android's standard programming language .

summary :
Java: Webpage . Enterprise development , Common applications , Game backstage .

C and C++

C、C++、Java、PHP、Python What are they used to develop ?

C/C++ In theory, any development can be done , As long as there are appropriate hardware drivers and API, Characterized by high efficiency , Basically, it's the most efficient compiled language . Except in your system C/C++ No compiler has . In some systems C++ Compilers don't have , however C In general, they have . For now ,C Language is mainly used to develop the underlying modules ( Like driving , decoder , Algorithm implementation ), Service application ( such as web The server ) And embedded applications ( For example, the program in the microwave oven ).C++ You can also do this , But due to the C++ The complexity and standards of , People still prefer to use C To do it .C++ More suitable for more complex but especially need efficient facilities , Like big games , Some basic libraries , Large desktop applications .

summary :
C: System bottom , drive , Embedded development .
C++: Game development , On a large scale , High performance , Distributed program development .


C、C++、Java、PHP、Python What are they used to develop ?

javascript Sounds like java It matters , It doesn't matter , It's just like a name , It's like the relationship between Lei Feng tower and Lei Feng , Although only one word is missing . js There is no doubt that the most widespread application is in web front end . To put it simply , What the website sends you is a bunch of documents in various labels , and js Responsible for manipulating these documents to achieve some client dynamic effects .js It's not just that , current Node.js It can also be used for server-side development .

summary :
JavaScript Is the browser's scripting language , In general, and Html,CSS Learn these together , Main website front-end development , Show all kinds of cool pictures .


C、C++、Java、PHP、Python What are they used to develop ?

php You will often see these three words in the browser address bar , So no accident php It's used to develop websites . It's also web The king's language at the back end , Countless websites are running on the back end php Code .

summary :
PHP: Mainly network front end , For generating web pages . Or the whole thing web All servers use php, For example, many forum engines .


C、C++、Java、PHP、Python What are they used to develop ?

Python Thanks to its rich and powerful library , It's also called glue language , To be able to make various modules in other languages ( In especial C/C++) It's easy to connect . One common application is , Use Python Quickly prototype the program ( Sometimes even the final interface of the program ), And then there are specific requirements , Rewrite it in a more appropriate language , such as 3D Graphics rendering module in the game , Performance requirements are particularly high , You can use it C/C++ rewrite , And then encapsulated as Python Extension class libraries that can be invoked .Python Server development and Internet of things development . Information security , Big data processing , Data visualization machine learning , Internet of things development , All the major software api, Desktop application , Need to be python.

summary :
Python: Dynamic interpretation , High development efficiency , Open source , flexible , Low entry barrier .
