To learn VB well, the first thing is to read the theoretical knowledge carefully. If you don't understand anything, you can search for information online, or ask questions from Baidu, or ask teachers. The most important thing is to understand the meaning of knowledge points.
Second, don't let go of every example in the book. Enter each word into the computer, and then run it to see what the code means.
Third: don't memorize the grammar part. At the beginning, you don't have to get the range of integer variables is 32768 or something. I knew it from the beginning. What needs to be remembered are conditional statements and loop statements. This is very difficult for people who are new to programming. Be sure to understand the grammatical structure of these sentences. Master these, and you will master more than half of VB sentences!
Fourth: build a small program by yourself, and then write your own code according to the requirements of the program to see if these functions can be realized. Repeated understanding, revision and finally successful operation will be your greatest gain.
When you get started and can write some small codes, it will be easy to understand variables, their value ranges and their value ranges! !
Fifth: Never mind that VB has been eliminated. C and JAVA are the useful languages. What did you study in college? What you learn is the ability of self-learning, independent thinking, independent analysis and independent problem solving. You have learned that no matter what the subject is, no matter how difficult it is, you can handle it well, so naturally you will stand out among your classmates. VB is not a tool that you have to make a living, but a subject that needs to be studied before you, that's all!
Good luck with your studies!
