A method is just a function with a receiver argument.
You can only declare a method with a receiver whose type is defined in the same package as the method. You cannot declare a method with a receiver whose type is defined in another package (which includes the built-in types such as
You can declare methods with pointer receivers.
Go interprets the statement
(&v).Scale(5) since the
Scale method has a pointer receiver.
- Defining Variadic Functions: When defining a function, the
...operator allows you to specify that the function can take any number of arguments of a specified type. This is similar to variadic functions in other programming languages like C’s
- Passing Arguments to Variadic Functions: When calling a variadic function, you can use the
...operator to pass a slice as multiple arguments. The
Appendfunction is a variadic function that can take multiple integers as arguments. By writing
slice2..., you are essentially spreading out the elements of
slice2as individual arguments to the
