In this golang code, I am asking a person to enter his name. After entering the name, the data will be taken from the values1 variable, and as a result, they will be printed out with the given keys like this

Given result

Enter your name: samename

Here is the name: samename
Here is the email address: email one
Here is the job role: job one

I also want to print the data of the values2 variable that is commented. Similarly, if I have the n number of values, will I have to repeat the for i := range values1 again and again?

Required result

Enter your name: samename

Here is the name: samename
Here is the email address: email one
Here is the job role: job role one

Here is the name: samename
Here is the email address: email two
Here is the job role: job role two
...
...

Code

package main

import "fmt"

func main() {
    var name string
    keys := [3]string{"name", "email address", "job role"}
    values1 := [3]string{"samename", "email one", "job role one"}
    // values2 := [3]string{"samename", "email two", "job role two"}

    for {
        fmt.Printf("Enter your name: ")
        fmt.Scanln(&name)
        fmt.Println()

        if name == values1[0] {
            for i := range values1 {
                // j is index into keys
                j := i % len(keys)

                // Print blank line between groups.
                if j == 0 && i > 0 {
                    fmt.Println()
                }
                fmt.Printf("Here is the %s: %s\n", keys[j], values1[i])
            }
            break
        } else {
            fmt.Println("Name is not found. Try again!")
        }
    }
}

CodePudding user response：

if you need to print the keys, maybe you can use map. with map you can print both of key and value.

package main

import "fmt"

func main() {
    var name string
    value1 := map[string]string{"name": "samename", "email": "email one", "role": "job role one"}
    value2 := map[string]string{"name": "samename", "email": "email two", "role": "job role two"}
    values := []map[string]string{value1, value2}
    var found bool

    for {
        fmt.Printf("Enter your name: ")
        fmt.Scanln(&name)
        fmt.Println()

        for _, value := range values {
            if value["name"] == name {
                found = true
                for k, v := range value {
                    fmt.Printf("Here is the %s: %s\n", k, v)
                }
                fmt.Println()
            }
        }

        if found {
            break
        } else {
            fmt.Println("Name is not found. Try again!")
        }
    }
}
