2. C# Basic knowledge compilation: Basic knowledge (13) Exception
Introduction: Often when we write code, we always encounter certain problems during operation that cause the program to crash. This is not because the programmer's level is not good, but because of problems with the business logic, operating system, or other equipment such as computers. For example, some methods in user32.dll are often used in C#. If this file is deleted , your program still cannot run. Of course, as a skilled programmer, you always need to take various situations into consideration when writing a program. The higher the level, the more situations you have to consider, and the more you consider, the less chance your program will crash. The better the robustness.

#5.Novice PHP Code
Introduction: I am a newbie asking for help with PHP code. I have graduated from high school in ten days. I have built a class website, which is a complete site in PHP (EMLOG3.5). I want to add it before accessing the website. Password verification requires that you cannot access any page of the website without passing the password first. I originally wanted to write it in HTML, but the password can be found in the source code, which is useless. I would like to ask an expert to help me write the complete code as much as possible.

How to convince my cousin to give up training and go to the third level? Introduction: My cousin took the college entrance examination, but his score was not ideal. He could only go to three undergraduate or junior colleges. His family was not rich, and tuition was a burden. But the annoying thing is that many Training institutions use the summer vacation to brainwash students everywhere, saying that after three or four years of college, they still can't find a job. It's not worth spending their parents' hard-earned money to go to a rubbish college. It's better to learn a skill and make money early, and spend some money on it. A high school graduate participated in training, and his graduation salary was 6.5K (fortunately, few people use Bill Gates as an example). In short, when my cousin came back, he had a lot of leaflets from various organizations in his hands, talking about them one after another. As a programmer who graduated from an ordinary second degree, I deeply understand 8. How to write a snake in Python from scratch? Introduction: PS: I feel like I’m being treated as a bastard.

The char array stores character sequences in C language and is declared as char array_name[size]. The access element is passed through the subscript operator, and the element ends with the null terminator '\0', which represents the end point of the string. The C language provides a variety of string manipulation functions, such as strlen(), strcpy(), strcat() and strcmp().

In C, the char type is used in strings: 1. Store a single character; 2. Use an array to represent a string and end with a null terminator; 3. Operate through a string operation function; 4. Read or output a string from the keyboard.

In C language, special characters are processed through escape sequences, such as: \n represents line breaks. \t means tab character. Use escape sequences or character constants to represent special characters, such as char c = '\n'. Note that the backslash needs to be escaped twice. Different platforms and compilers may have different escape sequences, please consult the documentation.

The usage methods of symbols in C language cover arithmetic, assignment, conditions, logic, bit operators, etc. Arithmetic operators are used for basic mathematical operations, assignment operators are used for assignment and addition, subtraction, multiplication and division assignment, condition operators are used for different operations according to conditions, logical operators are used for logical operations, bit operators are used for bit-level operations, and special constants are used to represent null pointers, end-of-file markers, and non-numeric values.

The difference between multithreading and asynchronous is that multithreading executes multiple threads at the same time, while asynchronously performs operations without blocking the current thread. Multithreading is used for compute-intensive tasks, while asynchronously is used for user interaction. The advantage of multi-threading is to improve computing performance, while the advantage of asynchronous is to not block UI threads. Choosing multithreading or asynchronous depends on the nature of the task: Computation-intensive tasks use multithreading, tasks that interact with external resources and need to keep UI responsiveness use asynchronous.

In C language, char type conversion can be directly converted to another type by: casting: using casting characters. Automatic type conversion: When one type of data can accommodate another type of value, the compiler automatically converts it.

There is no built-in sum function in C language, so it needs to be written by yourself. Sum can be achieved by traversing the array and accumulating elements: Loop version: Sum is calculated using for loop and array length. Pointer version: Use pointers to point to array elements, and efficient summing is achieved through self-increment pointers. Dynamically allocate array version: Dynamically allocate arrays and manage memory yourself, ensuring that allocated memory is freed to prevent memory leaks.

A strategy to avoid errors caused by default in C switch statements: use enums instead of constants, limiting the value of the case statement to a valid member of the enum. Use fallthrough in the last case statement to let the program continue to execute the following code. For switch statements without fallthrough, always add a default statement for error handling or provide default behavior.
