What is asp.net? What is asp.net used for? Many people may have such questions. Let's summarize asp.net.
What is asp.net?
ASP.NET, also called ASP, is also an upgrade of asp. It can build powerful web applications and is suitable for the infrastructure and various services required by PCs and mobile devices. ASP also integrates the advantages of the old ASP version and refers to development languages such as Java, adding many new features and modifying the running errors of the previous ASP version.
What are the features of asp.net language?
Multiple Chinese language support is ASP. NET a feature, ASP. NET has many types of languages and relatively strong language functions, and is used in ASP. NET, the code in the page is edited and does not need to be compiled again when requested a second time. It also supports web services and creates different authorization methods for users to ensure the security of roles.
What are the differences between asp.net and ASP?
asp.net and ASP were born at different times. ASP is earlier than asp.net. And there are certain differences in development methods and development environments. ASP compiles and executes mechanically at the same time. Of course, the effect is relatively low, while asp.net is a compiled framework that directly runs the compiled code in the server. This in turn can improve the effect.
The above is a complete introduction to what asp.net is. If you want to know more about ASP.NET video tutorial, please pay attention to the php Chinese website.

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().

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 core concepts of .NET asynchronous programming, LINQ and EFCore are: 1. Asynchronous programming improves application responsiveness through async and await; 2. LINQ simplifies data query through unified syntax; 3. EFCore simplifies database operations through ORM.

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.

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.

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.

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.

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.
