Go by Example:variadic Functions

The Variadic function supports any number of incoming parameters. For example: FMT. PRINTLN is a common variable-parameter function.

Package Mainimport "FMT"//This function can use any number of int types as parameter func sum (nums ... int) {    fmt. Print (Nums, "")    total: = 0    for _, num: = range Nums {Total        + = num    }    fmt. Println (total)}func main () {    //Variadic function support is used in a regular manner,    //also supports only one    sum (1, 2)    sum (1, 2, 3)    // If you need an incoming parameter in a slice, like the following    //"func (Slice ...)" Break the slices into the    nums: = []int{1, 2, 3, 4}    sum (Nums ...)}

The output is:

<strong>$ Go run variadic-functions.go </strong>[1 2] 3[1 2 3] 6[1 2 3 4] 10

Another important feature of functions in the go language is the construction of function closures. We will explain in the next section.
