index this text 4 1 parseInt this text 1 means

You can only guess based on the information you provide, $(this).text() is the text information of the dom element, which should be the ordinal number of the current carousel**, you can guess that there are a total of 4 frames in this carousel, index=a?b:

C The question mark expression is, if A is true, return B, otherwise, return C, which means that if the current sequence number is greater than the total number of frames 4, it will change back to 1, start from the beginning, if it is less than 4, add 1, because text() returns the number of the character type, so it needs to be converted into a number for calculation.

The so-called framework is a large number of classes that have been written, so to speak. In addition to a large number of classes, there may be some rules, such as naming, paths, etc. If this rule is followed, the methods provided by the framework library are called.

In addition, the framework has nothing to do with open source or not, open source just means that you can get the source of the framework, and what is not open source just can't see the source.

Like what. .NET itself is not open source, but there are many frameworks that are, such as the most well-known servicestack

Open source and free are different concepts, open source software has many different kinds of licenses, some can be modified and used at will, some can be used in non-commercial projects, and some need to be paid.

The same language, no need to switch. Don't worry, just ignore it boldly. What you can't ignore will jump in front of your eyes, and then you will know the difference. It's a question that doesn't need to be thought about at all.

C cannot be executed directly.

Did you hear that C is directly executed?

Programming languages are commonly known as "computer languages", and there are many types, which can be divided into three categories: machine languages, assembly languages, and high-level languages. Every action and step done by the computer is executed according to the program that has been programmed in the computer language, and the program is a collection of instructions to be executed by the computer, and the program is all written in the language we know. Therefore, if people want to control the computer, they must issue commands to the computer through the computer language.

There are two forms of general-purpose programming languages: assembly languages and high-level languages.

Since the computer can only accept binary ** internally, the instructions described by binary **0 and 1 are called machine instructions, the set of all machine instructions constitutes the machine language of the computer, and the program programmed in machine language is called the target program.

With the development of the market, python has become one of the four major programming languages, which is very friendly to beginners and easy to get started, especially in the era of artificial intelligence and data analysis.

It's normal for universities to not keep up with the pace of the times. Can learn about python to understand old boys

What is the importance of Python in programming languages? No status; It's not a classic, and it's not too popular.

It really doesn't matter whether the university teaches or not, so many languages, is it possible that every one of them has classes?

It has a hairy relationship between teaching and not teaching in college. 、

There are so many languages, do you have classes for everyone?

There is no such software and no such operation, because the main difficulty in programming is logic and algorithms, not simple word translation.

For example: it is like translating English into Chinese to understand, but now you can't even understand Chinese, what is the use of translation, and programming is more complex than learning Chinese and English, design to logic and algorithms, and a lot of practice and experience.

It's a great compiler, and I like it.

Programming languages are used for interaction between programmers and machines.

Programming languages are used for interaction between humans and computers?

Eventually, high-level languages will have to be translated into machine languages that computers can read.
