What are some examples of variadic functions in Go?

Variadic functions in Go allow you to pass a variable number of arguments. For example, the built-in fmt.Println function is a variadic function.

Can you show me how to define a variadic function?

Sure! You can define a variadic function like this: func sum(nums ...int) int { ... }. The ... indicates that nums can take multiple integer arguments.

What about using variadic functions with different types?

In Go, variadic functions can only accept one type. However, you can use an interface{} type to accept any type, but you'll need to handle type assertions inside the function.

Can you give me a practical example of a variadic function?

Certainly! Here's a simple example: func concatenate(strs ...string) string { ... } can be used to concatenate multiple strings into one.
