The variable parameter function in 014_go language

Code Demo

package mainimport"fmt"func sum(nums ...int) {    " ")    0    forrange nums {        totol += num    }    fmt.Println(totol)}func main() {    sum(12)    sum(123)    nums := []int{1234}    sum(nums...)}

Code Run Results

[1 2] 3
[1 2 3] 6
[1 2 3 4] 10

Code interpretation:

• Variable parameter, which can pass any number of arguments at the time of the call
• The function is the func name (args ... type), which accepts any number of type values as arguments
• If you have a slice slice with multiple values and want to use them as arguments, you must call Func (slice ...) as such.
