The definition of overloaded functions: several functions within the same scope have the same name but different parameter lists, called overloaded functions. Here is an important premise: the same scope;If the overloaded function is defined in a

In C + +, the concept of function templates is introduced to save code. Not only functions have templates, but classes also have templates. Now let's write a class template.Template class AAA {private:t t;public:void test_func (const t& t); void

C # Extension methods (Extend method)Add a method to the class without changing the original class.1, the extension method must be written in a static class2, the extension method must be a static method, although it is a static method, but this

One, value parameterA parameter that is not declared with a ref or out modifier is a value parameter. The value parameter is used to pass the data to the method by copying the value of the argument to the formal parameter. When the method is called,
