英文:
Syntax for me to input values in Go Language
问题
我一直在寻找一种在C语言中实现以下语法的方法：
scanf("%d",&num);
我发现在Go语言中可以使用以下语法：
fmt.Scanf("%d",&num)
问题是，当我使用它两次时，它不允许我在第二部分输入值。
示例：
package main
import "fmt"
func main() {
var name string
var age int
fmt.Print("Enter your name: ")
fmt.Scanf("%s", &name)
fmt.Print("\nEnter your age: ")
fmt.Scanf("%d", &age)
fmt.Println(name,"is",age,"years of Age")
}
输入示例：name=Jack，age=18（这是问题的一部分，它不允许我为年龄输入值）
它将显示：
Jack is 0 years of age
英文:
I've been looking for a way how to have a syntax like this in C
scanf("%d",&num);
and I've found out in Go Lanuguage you can use this
fmt.scanf("%d",&num)
The problem is when I'll use it twice, it doesn't allow me to enter a value on the second part.
Example:
package main
import "fmt"
func main() {
var name string
var age int
fmt.Print("Enter your name: ")
fmt.Scanf("%s", &name)
fmt.Print("\nEnter your age: ")
fmt.Scanf("%d", &age)
fmt.Println(name,"is",age,"years of Age")
}
Sample input name=Jack and age=18(this is the part of the problem wherein it doesn't allow me to input for the age)
it will display
Jack is 0 years of age

你可以将最后一行替换为以下内容：
fmt.Printf("%s的年龄是%d岁", name, age)
以下是完整的代码：
package main
import "fmt"
func main() {
var name string
var age int
fmt.Print("请输入你的名字：")
fmt.Scanf("%s", &name)
fmt.Print("请输入你的年龄：")
fmt.Scanf("%d", &age)
fmt.Printf("\n%s的年龄是%d岁\n", name, age)
}
输出结果：
请输入你的名字：rex
请输入你的年龄：33
rex的年龄是33岁
英文:
You can replace the last line with this:
fmt.Printf("%s is %d years of age", name, age)
Here is the full code:
package main
import "fmt"
func main() {
var name string
var age int
fmt.Print("Enter your name: ")
fmt.Scanf("%s", &name)
fmt.Print("Enter your age: ")
fmt.Scanf("%d", &age)
fmt.Printf("\n%s is %d years of age \n", name, age)
}
Output :
> Enter your name: rex
>
> Enter your age: 33
>
> rex is 33 years of age

请尝试这个代码：
package main
import (
"bufio"
"fmt"
"os"
"strings"
)
func main() {
r := bufio.NewReader(os.Stdin)
fmt.Print("请输入您的姓名：")
name, _ := r.ReadString('\n')
fmt.Print("请输入您的年龄：")
age, _ := r.ReadString('\n')
name, age = strings.TrimSpace(name), strings.TrimSpace(age) //去除 \n
fmt.Println(name, "是", age, "岁")
}
这是一个简单的Go语言代码，它会要求用户输入姓名和年龄，并将其打印出来。
英文:
Try this:
package main
import (
"bufio"
"fmt"
"os"
"strings"
)
func main() {
r := bufio.NewReader(os.Stdin)
fmt.Print("Enter your name: ")
name, _ := r.ReadString('\n')
fmt.Print("Enter your age: ")
age, _ := r.ReadString('\n')
name, age = strings.TrimSpace(name), strings.TrimSpace(age) //remove \n
fmt.Println(name, "is", age, "years of Age")
}
