Assign the following data using slice literals to the slices that // you've declared in the first exercise. // // 1. The names of your three best friends (to the names slice) // // 2. The distances to five different locations (to the distances slice) // // 3. Five bytes of data (to the data slice) // // 4. Two currency exchange ratios (to the ratios slice) // // 5. Up/Down status of four different web servers (to the alives slice) // // 2. Print their type, length and whether they're equal to nil value or not // // 3. Compare the length of the distances and the data slices; print a message // if they are equal (use an if statement). // // // EXPECTED OUTPUT // names : []string 3 false // distances: []int 5 false // data : []uint8 5 false // ratios : []float64 2 false // alives : []bool 4 false // The length of the distances and the data slices are the same. // --------------------------------------------------------- func main() { var ( names []string // The names of your friends distances []int // The distances data []byte // A data buffer ratios []float64 // Currency exchange ratios alives []bool // Up/Down status of web servers ) names = []string{} distances = []int{} data = []byte{} ratios = []float64{} alives = []bool{} fmt.Printf("names : %T %d %t\n", names, len(names), names == nil) fmt.Printf("distances: %T %d %t\n", distances, len(distances), distances == nil) fmt.Printf("data : %T %d %t\n", data, len(data), data == nil) fmt.Printf("ratios : %T %d %t\n", ratios, len(ratios), ratios == nil) fmt.Printf("alives : %T %d %t\n", alives, len(alives), alives == nil) }
