Easy Language Program Error Code 1 Array member references subscripts are out of the definition rang

This error occurs because you are accessing an array element that is outside the range defined by the array, e.g. if you define an array[10], but you want to access array[100].

Solution: Your subscript reference is out of bounds beyond the length of this array, please post your **, or modify the subscript yourself.

Increases the number n in [n] when the array is defined.

Or when using array members, the number m in [m] is less than or equal to n-1

Example: If the defined array is a[10].

The available subscript is: 0-9

1. Reason: Because the array members taken out do not exist, assuming that the array to be taken only has 2 members, and the third member is taken, it will definitely prompt this error.

2. General easy language.

Programmers use regular expressions.

Split text, when getting text from the network for splitting, array member reference subscript is out of the defined range.

3. The prevention method is very simple, that is, when taking the array members, first judge whether the number of array members is normal.

The command you need to use is to take the number of array members (), which is described in detail in the easy language.

The game,How did you get the program design?,That's to explain the program problem to you.,The array index is out of range.,In layman's terms, there are ten rooms on the 1st floor.,You're going to enter the 11th.,The administrator doesn't do it.,Don't let you go.。 That's what it means.,You can't change it.,Because the game is encapsulated.,I advise you to re-follow the next one.,Or restart the computer.,It's estimated that it's just been updated.,There are bugs after the general update.

This is because the range of the value is beyond the data in the database, that is, it does not rely on the data value in the database, so this kind of prompt will definitely appear, for example, there are only two data 1 and 2 in the database, but the value of 3 in the programmed program will be taken, which will cause the database to not recognize, and then the program will be interrupted.

The general easy-language programmer will use regular expressions, clear things to cut the text, and get the text from the network for segmentation, and the array member reference subscript is beyond the definition range.

The average easy language programmer will use regular expressions, split the text, and get the text from the network for segmentation, and the array member reference subscript is beyond the definition range.

1. This is talking about the array element to be taken, which does not exist in the array.

2. For example, if you define an array of 5 elements, and use it to get the 6th element, it will cause the above error.

3. In addition, the subscript of the e language array starts from 1, and if you take the 0th element, it is also wrong.

4. Diagram: 5. Modification method: take the elements within the defined range or expand the range of the array.

According to what you said, if it is a hint that the subscript of the array member reference is out of the definition range, it should be a problem of returning the array, once the members of the returned array are less than 3, then the return array you wrote [3] will prompt such an error, you check the number of members of the returned array.

Reason for error: The byte set of your "general ** content" is estimated to be empty (not obtained), or there is no byte set of Chinese colons in the middle, so that after splitting, it will definitely not become an array, right, that is, the number of array members is 0, and your next line ** directly uses the split content [1], referencing a non-existent array element, it will definitely be wrong.

How to improve: Before using the split content[1], check the number of members of the array, use the command "take the number of array members ()", and then determine whether its value is 0, and then reference the array element. (In the future, you must check before programming using arrays, so that it is not easy to cause bugs.) ）

If your general ** content must contain the byte set of Chinese colons. That is, there was a failure in the data you retrieved before, and the data you retrieved was empty. Check the check.

But also look at method 1, it's better to write an exception handler, otherwise the program will hang once it crashes.

1l is very detailed, to put it simply, because there is no division of things, so this array is an empty array (0), and the subscript is 1, which is out of range and reports an error.

Since you're an array member, the subscript is out of the index, why don't you change it back? Use in the scope, if you don't know **exceeded, just use debugging to see, where there are loops, where there are indexes, you pay attention to how big the subscript you use, how much your definition is, you can find the problem, debugging is very troublesome, you try.

What is the purpose of this array? What is it used for?

During software development, it's normal for things to go wrong. What should I do in the face of mistakes?

1.Adjust your mindset.

Don't feel it"What should I do if something goes wrong and can't solve it? "There are very few mistakes that are really difficult to solve, and in the vast majority of cases, as long as the thinking is clear, carefully investigated, and carefully designed, it can be properly solved.

Don't keep thinking about it, either"It can't be, it shouldn't be wrong. "It's already wrong, that's wrong, nothing is impossible. What we need to do now is to analyze the problem, solve the problem, and don't think too much about other aspects and waste time.

At the same time, be sure to calm down and take it seriously. **Behind most mistakes, there is a mindset at work. If you don't carefully reorganize your thinking and let your mindset continue, you will often lose a lot of time and make progress.

2.Investigate carefully.

3.Fix it properly.

4.Review Summary.

Retrospective summaries are very important. If you ignore the review and summary, it will be difficult to improve your error handling skills, and you will still encounter a steady stream of errors in the future, and you will not be able to deal with them.

Looking back on the handling process of this error, have you taken any detours, and how can you improve it in the future?

What is the problem with this error? Can you think of a way to avoid these kinds of mistakes? Or, mistakes are hard to avoid, but make it easier to troubleshoot and fix them?

The reason for this error is that there is a misunderstanding in the developer's thinking?

In the process of software development, it is not cost-effective to spend a lot of time and energy dealing with various errors. Improving your error handling skills and freeing up your time and energy is the way to go.

This can't be seen just by looking at **, because whether there is an error or not is related to the data, and you have no data to shoot it.

For example: <>

If the + sign part is wrong, it may be that there are no four parts after the variable [3] is divided. So this kind of error needs to be debugged, and others can't see ** Potato to help you change it.

Use Fetch Number of Array Members () to debug the array and try to call the error.
