# 读取用户的输入
|
||||||
|
|
||||||
|
我们如何读取用户的键盘(控制台)输入呢?从键盘和标准输入(os.Stdin)读取输入,最简单的办法是使用 `fmt` 包提供的 Scan 和 Sscan 开头的函数。请看以下程序:
|
||||||
|
|
||||||
|
Listing 12.1—readinput1.go:
|
||||||
|
|
||||||
|
```go
|
||||||
|
// read input from the console:
|
||||||
|
package main
|
||||||
|
import "fmt"
|
||||||
|
var (
|
||||||
|
firstName, lastName, s string
|
||||||
|
i int
|
||||||
|
f float32
|
||||||
|
input = "56.12 / 5212 / Go"
|
||||||
|
format = "%f / %d / %s"
|
||||||
|
)
|
||||||
|
func main() {
|
||||||
|
fmt.Println("Please enter your full name: ")
|
||||||
|
fmt.Scanln(&firstName, &lastName)
|
||||||
|
// fmt.Scanf("%s %s", &firstName, &lastName)
|
||||||
|
fmt.Printf("Hi %s %s!\n", firstName, lastName) // Hi Chris Naegels
|
||||||
|
fmt.Sscanf(input, format, &f, &i, &s)
|
||||||
|
fmt.Println("From the string we read: ", f, i, s)
|
||||||
|
// output: From the string we read: 56.12 5212 Go
|
||||||
|
}
|
||||||
|
```
