I am writing a code in go language using cobra, currently the input Im giving is :
Calc add
Enter the Number of inputs
2
Enter the Numbers
2
4
Output: Sum is : 6
In this those who are familiar with cobra, Calc is my project and add is the command Im using,I want the input to be given as Calc add N2 2 4( in a single line) and the output should be displayed, where N is a variable that identifies the Number of inputs and 2 4 are the numbers to be added.
CODE FOR THE ADD COMMAND:
package cmd
import (
"fmt"
"github.com/spf13/cobra"
)
// addCmd represents the add command
var addCmd = &cobra.Command{
Use: "add",
Short: "Addition value of given Numbers",
Run: func(cmd *cobra.Command, args []string) {
length := 0
fmt.Println("Enter the number of inputs")
fmt.Scanln(&length)
fmt.Println("Enter the inputs")
numbers := make([]int, length)
for i := 0; i < length; i++ {
fmt.Scanln(&numbers[i])
}
fmt.Println(numbers)
sum:=0
for _, numbers := range numbers {
sum += numbers
}
fmt.Println("The Sum :",sum)
},
}
func init() {
RootCmd.AddCommand(addCmd)
}
