~What does 1 mean and how to express it in C language?

~1 represents in C language

In C language, The symbol represents the logical NOT operation (bitwise negation). It inverts each binary bit in the operand, i.e. 0 becomes 1 and 1 becomes 0.

Syntax:

~operand

Among them, operand is the expression to be bitwise inverted.

Example:

int x = 5; // 二进制表示:0101
int y = ~x; // 二进制表示:1010

In this case, the value of y is -6 because the binary representation after bitwise negation is 1010, converted to decimal is -6.

Note:

  • ~ The operator has a higher priority than other arithmetic operators (such as addition, subtraction). The
  • ~ operator can be applied to any integer type of data, including int, long, and short.

C# is a modern, object-oriented programming language developed by Microsoft and as part of the .NET framework. 1.C# supports object-oriented programming (OOP), including encapsulation, inheritance and polymorphism. 2. Asynchronous programming in C# is implemented through async and await keywords to improve application responsiveness. 3. Use LINQ to process data collections concisely. 4. Common errors include null reference exceptions and index out-of-range exceptions. Debugging skills include using a debugger and exception handling. 5. Performance optimization includes using StringBuilder and avoiding unnecessary packing and unboxing.

Testing strategies for C#.NET applications include unit testing, integration testing, and end-to-end testing. 1. Unit testing ensures that the minimum unit of the code works independently, using the MSTest, NUnit or xUnit framework. 2. Integrated tests verify the functions of multiple units combined, commonly used simulated data and external services. 3. End-to-end testing simulates the user's complete operation process, and Selenium is usually used for automated testing.
