- How to implement the power function in C language
- In C language, there are two ways to implement the exponentiation operation: use the pow() function to calculate the power of the second parameter of the first parameter. Define a custom power function, which can be implemented recursively or iteratively: the recursive method continues to double the power until it is 0. The iterative method uses a loop to multiply the base one by one.

- What is the difference between operators ? and ?? in c#
- The ? and ?? operators are conditional operators used to select values. The ? operator throws an exception if either operand is null, the ?? operator handles null values safely and returns the right operand if the left operand is null.

- Operator precedence in c#
- The precedence of operators in C#: unary operators () + (positive sign), - (negative sign), ! (logical NOT), ~ (bitwise NOT) * (multiplication), / (division), % (taking remainder) + (addition), - (subtraction) < (less than), <= (less than or equal to), > (greater than), >= (greater than or equal to), == (equal to), != (not equal to) && (Logical AND), || (Logical OR), ^ (Logical XOR)?:: (Condition? true_expression : false_expression)= (Assignment), +=, -=, *=, /= (Composite assignment)

- What does it mean in c#?
- The ? operator (null coalescing operator) in C# is used to provide an alternative value when a variable may be null. The syntax is variableName ?? defaultValue, if variableName is not null, its value is returned, otherwise an alternative value is returned. It provides the advantages of simplicity, readability, and avoidance of null pointer exceptions.

-
- What does ?? mean in c#?
- The ?? operator (null coalescing operator) in C# provides an alternative value for null operands: checks whether operand x is null. If x is not null, return the value of x. If x is null, returns the alternative value expression y.

- What does @ mean in c#
- The @ symbol in C# removes the escaped meaning of special characters, allows strings to span multiple lines, allows Enum members to customize the underlying value, and indicates that a method or property is asynchronous.

- In c#: what is the operator?
- In C#, operators are symbols that perform operations on variables, including: Arithmetic operators: Perform mathematical operations such as addition, subtraction, multiplication, and division. Relational operators: Compare two expression values, such as equal to, not equal to, greater than, and less than. Logical operators: perform logical operations on Boolean values, such as AND or XOR. Bit operators: perform operations on binary bits, such as AND, XOR, left shift and right shift.

- Usage of @ in c#
- The @ symbol in C# is used to create verbatim strings, which are strings that do not escape special characters, including double quotes, backslashes, tabs, newlines, and carriage returns. This simplifies the content of strings containing special characters and improves readability, but compiler behavior will be affected. When using @ strings, be careful not to use string interpolation to create or concatenate with non-verbatim strings.

- What does += mean in c#
- The += operator in C# is used to accumulate values to variables, and its syntax is variable += value. It first calculates the value of value, then adds it to the current value of the variable, and finally reassigns the result to the variable.

- c#:what is
- Answer: The nameof operator in C# returns the name of the specified expression. Detailed description: The nameof operator can be used in the following type expressions: Field Attribute Method Event Type Type Member (field, property, method, etc.)

-
- What is /// in c#
- Multi-line comments in C# start with /// symbols and can span multiple lines and document the purpose of the code element. Such annotations are used for documentation purposes, generate XML documentation, and enhance code readability and maintainability, while also supporting IntelliSense in tools such as Visual Studio.

-
- What does += mean in c#
- The += operator in C# is used to add a value to an existing variable or property. It is equivalent to assigning a value to the variable or property and then adding a value. This operator works with numeric types to update values one by one, accumulate, or simplify code.

-
- What does // mean in c#
- In C#, // represents a single-line comment, used to add additional information that does not affect the running of the code. The syntax is: // Comment content. Unlike multiline comments (/multiline comment content/), single-line comments apply to only one line and provide additional explanation about a code fragment, variable, method, or class.

-
- The role of @ in c#
- The functions of the @ symbol in C# include: string literal indicator (allows the use of unescaped backslashes), string interpolation (prevents special characters in expressions from being parsed), native strings (converted to text at compile time) As well as avoiding keyword conflicts (by being a prefix).

-
- What does ? in c# mean?
- The ?. operator (null coalescing operator) is used to safely access properties or methods that may be null, avoiding NullReferenceException, simplifying code and improving readability. It will return the value of the property or method if present, otherwise it returns null.
