First of all, math is not very good and does not affect programming much, and the foundation of programming in mathematics is"Calculation method:"For example, if you write a program to complete a function, someone else has written a program to complete the same function as yours. You both use the same language, but running on an equally configured machine, your program is slower than his. This is the result of your calculation being different from others.
Beginners may be confused about what language to learn. In fact, that kind of language can be, it just depends on what you do, if you write a database program with VFP, you can do it with VFP, if you write a program that deals with hardware, then you have to C, etc.
Current. .net heard about it. It's a very good framework that allows you to integrate programs written in various languages in one project.
Also, all kinds of languages are interconnected, as long as one language is known, other languages will be learned, and the difficulty is that the IDE environment of each language is not easy to use. It also includes functions in the environment, etc.
Live and learn.

VB is useless, VB is also very reusable, just look in which direction to do it. If you want to do system-level development, use C++ if you do application development VB can upgrade to.
A lot of commercial software, data management software is developed by VB, VB is simple and the development cycle is fast, but to learn programming well, you must learn the API and way of thinking well, I wish you success on the road to programmer.
After all, it is helpful to apply API and some program logic thinking, and it is okay if you have to learn it independently. It depends on how to choose. Both.
Operates under the NET framework and facilitates cooperation in the development of international standards.

It is recommended to read some books such as Introduction to Computer Science first, learn some basic computer knowledge, so that it is better when you go to learn programming, my college major is computer science and technology, that is, to learn programming, we started from this course, and then learned C language, then C++, and then learned data structures. In fact, it is good to learn a programming language, and once you understand it, it will be easy to get started when you are exposed to other languages.

In fact, it doesn't matter whether he is eliminated or not, the first language is very important. However, I personally feel that it is better to learn C language for the first time, whether it is VB or C, after being proficient in one language, it will be very simple to learn the second one. It's not that you can only make things out of this if you learn anything.
If you're looking for a job, it's not enough to speak a language. But no matter what the language, the methods are almost the same, and if you learn more, you will find that they are actually the same.

You can try to learn. The net side, such as C, etc., is similar to VB, and it is relatively easy to turn around, but you have to learn the database again.
-
You can learn C, or C++ C (C is used more).
1. At the beginning, you can just read some basic rules such as grammar, you don't necessarily have to understand it in particular, you can try a few things yourself according to the examples in the book, cultivate confidence, and always give yourself a little encouragement.
2. When the basic skills are almost complete, go to the books on data structures and numerical algorithms to understand the knowledge of data access. No matter what language you're learning, these are must-haves, unless you're just trying to get a taste of programming.
3. Try to do as many exercises as possible, and it is best to participate in some projects, or study the examples of others doing.
Programming is the Chinese abbreviation of writing programs, that is, to let the computer solve a certain problem on behalf of the computer, to stipulate a certain calculation method for a certain computing system, is the process of the computing system to run according to the calculation method, and finally get the corresponding results.
In order for the computer to understand human intentions, human beings must tell the computer the ideas, methods and means of the problem to be solved in a form that the computer can understand, so that the computer can work step by step according to human instructions and complete a specific task. This process of communication between people and computing systems is programming.
Pay attention to develop a good programming style and writing habits during the learning process. You might as well go to the famous programming forums in China to see the posts, especially the essence posts, communicate with others more, and gain a lot. As for the amount of time you spend studying each day, it varies depending on your interest and patience, but the most important thing is not the length of time, but the feeling that you have gained something every day.

Programming is actually the use of a specific language to control a computer, or to communicate with a computer.
As a beginner, you need to master the following basics to get started.
1. Installation and use of programming environment. For example, the learning of Python is generally recommended for the software that comes with the IDLE, which is simple and easy to use.
2. Master the use of input and input statements. An input statement lets the computer know what you typed on the keyboard, and an output statement lets you know the result of the computer's execution. Take the output statement as an example:
The content in "" is the as-is output, separated by multiple output items.
3. Master the use of operational (including calculation and logic) expressions. This is mainly a formula that uses symbols such as + and - to express calculation or comparison, so that the computer can make calculations or judgments.
One is a calculated expression and the other is a so-called logical expression.
4. In particular, it is necessary to master the use of assignment expressions, which is mainly the understanding of equals. In computer programming languages, the equals sign generally does not mean equality, but rather assignment. That is, the content to the right of the equal sign is written into the name on the left.
5. Understand and be proficient in the use of variables, which literally mean the amount that will change. Its physical role is to memorize information. You can find the memorized content by giving it a name to the content you want to memorize, and then you can find the memorized content by that name. Somewhat similar to the letters in mathematics represent numbers.
6. Select the structure, which is the basis for the computer to have a certain ability to choose and judge. For example, our common login, VIP needs to use the selection structure. Because we have listed all kinds of situations in the program, the program will have various changes.
No choice, no change! The root of change lies in the conditions.
7. Loop structure, which is to make the computer have the ability to repeat. The premise is that the event should have a certain regularity, such as 1, 3, 5, 7, 9 ......
If there are no rules, it is also possible to construct them by means such as arrays.
In fact, range() represents the range, and the three parameters represent the start, end, and interval respectively. The end cannot be exceeded, and the interval can be positive or negative.
8. Reading and writing of files, which is mainly for a large amount of data processing.
Generally speaking, mastering these basics is considered an introductory knowledge. Please correct any deficiencies.

1.Learning to code starts from the ground up, and theoretically requires extensive reading. Understand the breadth and depth of algorithms and the basic theories of computers.
2.Practically, there needs to be a wide range of exercises, and the breadth of practice lies in practicing different contents. Then there is the spirit of innovation and the ability to think mathematically, which need to be cultivated. The foundation must be laid well, and learning programming must have a certain foundation.
3.The cultivation of logical thinking ability and the learning of programming must have a certain logical thinking ability. The cultivation of "thinking ability" requires a long period of practical training.
To become a good programmer, the most important thing is to master programming ideas. To achieve this, it is necessary to gradually accumulate through repeated practice, observation, analysis, comparison, and summarization.

It is necessary to learn the installation of programming, the use of programming, the language of programming, the input method of programming, and the calculation method of programming.
