@param是干嘛的

In the context of programming, especially in languages like C++, Java, and C#, the keyword `@param` is typically used in documentation comments or annotations to describe function parameters. When documenting a function, you place the `@param` tag followed by the parameter name, its type, and a brief description of what that parameter represents within the function's functionality.

For example:

/**
 * @param name String The name of the person being greeted.
 * @param age int The age of the person.
 */
void greet(String name, int age) {
    // Function body...
}

Here, `@param name String` explains that `name` is a string parameter, and `@param age int` indicates that `age` is an integer parameter. This helps developers understand how to use the function correctly and provides a reference for future maintenance or code reading.
