Golang类型转换

Question

I have specific questions for my project

input = "3d6"

I want to convert this string some parts to integer. For instance I want to use input[0] like integer. How can I do this?

Answer 1

For example,

package main

import (
    "fmt"
)

func main() {
    input := "3d6"
    i := int(input[0] - '0')
    fmt.Println(i)
}
