Consider the following variable declarations:
|
|
|
|
x, y, z := 10, 15.5, "Gophers"
|
|
score := []int{10, 20, 30}
|
|
|
|
Using fmt.Printf():
|
|
|
|
Print each variable using a specific verb for its type
|
|
|
|
Print the string value enclosed by double quotes ("Gophers")
|
|
|
|
Print each variable using the same verb
|
|
|
|
Print the type of y and score
|

package main

fmt.Printf("score is %#v\n", score)
