How to check if a string contains only letters and numbers using RegEx in Go

Answer 1

package main

import (
    "fmt"
    "regexp"
)

func isAlphanumeric(str string) bool {
    // Define the regular expression for alphanumeric characters
    alphanumericRegex := "^[a-zA-Z0-9]+$"

    // Compile the regular expression
    re := regexp.MustCompile(alphanumericRegex)

    // Use MatchString to check if the string matches the pattern
    return re.MatchString(str)
}

func main() {
    str := "VuZ3q7J4wo35Pi"

    if isAlphanumeric(str) {
        fmt.Println("The string contains only letters and numbers.")
    } else {
        fmt.Println("The string contains characters other than letters and numbers.")
    }
}
