Handling Errors in Go

Explore error handling in Go with a function that divides numbers, demonstrating how to create and handle custom errors.

package main

import (
    "fmt"
    "errors"
)

func divide(a, b float64) (float64, error) {
    if b == 0 {
        return 0, errors.New("division by zero is not allowed")
    }
    return a / b, nil
}

func main() {
    result, err := divide(10.0, 0)
    if err != nil {
        fmt.Println("Error:", err)
    } else {
        fmt.Println("Result:", result)
    }
}
