Article Introduction：Typical scenarios for function pointers include: callback functions, sorting functions, event handling, function tables, lazy loading and underlying API interoperability. By using function pointers, functions can be called indirectly at runtime, enabling dynamic and scalable code. For example, callback functions are used to call back when asynchronous events (for example, user input or network requests) occur, sorting functions are provided for custom comparison algorithms for different object types, and event handlers are used to register and handle different types of events (for example, mouse clicks or keyboard input), the function table is used to store multiple function pointers for conditional selective calls, lazy loading can delay the loading of function definitions until they are called for the first time, and the underlying API interoperability allows the use of different functions Signed interactions with other languages ​​or libraries.
