    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#
    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.

  • In c#: what is the operator?
    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#
    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.

  • The role of @ in c#
    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).
