The printPrimeNumbers function is called directly in the main function. It would be better to move this call to a separate function or an HTTP handler to improve modularity and maintainability.
| printPrimeNumbers(5,19) | |
| // start HTTP server with `http.DefaultServeMux` handler | |
| func main() { | |
| http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) { | |
| http.ServeFile(w, r, r.URL.Path[1:]) | |
| }) | |
| http.HandleFunc("/prime", primeHandler) | |
| // start HTTP server with `http.DefaultServeMux` handler | |
| log.Fatal(http.ListenAndServe(":9000", nil)) | |
| } | |
| func primeHandler(w http.ResponseWriter, r *http.Request) { | |
| printPrimeNumbers(5, 19) | |
| } |
| func printPrimeNumbers(num1, num2 int){ | ||
| if num1<2 || num2<2{ | ||
| fmt.Println("Numbers must be greater than 2 for this to work.") | ||
| return | ||
| } | ||
| for num1 <= num2 { | ||
| isPrime := true | ||
| for i:=2; i<=int(math.Sqrt(float64(num1))); i++{ | ||
| if num1 % i == 0{ | ||
| isPrime = false | ||
| break | ||
| } | ||
| } | ||
| if isPrime { | ||
| fmt.Printf("Found Prime number: %d ", num1) | ||
| } | ||
| num1++ | ||
| } | ||
| fmt.Println() | ||
| } |

The printPrimeNumbers function currently prints the prime numbers directly to the console. To make it more reusable, consider returning a slice of prime numbers instead of printing them. This way, the function can be used in different contexts, such as returning the prime numbers in an API response or processing them further.
| func printPrimeNumbers(num1, num2 int){ | |
| if num1<2 || num2<2{ | |
| fmt.Println("Numbers must be greater than 2 for this to work.") | |
| return | |
| } | |
| for num1 <= num2 { | |
| isPrime := true | |
| for i:=2; i<=int(math.Sqrt(float64(num1))); i++{ | |
| if num1 % i == 0{ | |
| isPrime = false | |
| break | |
| } | |
| } | |
| if isPrime { | |
| fmt.Printf("Found Prime number: %d ", num1) | |
| } | |
| num1++ | |
| } | |
| fmt.Println() | |
| } | |
| func printPrimeNumbers(num1, num2 int) []int { | |
| if num1 < 2 || num2 < 2 { | |
| fmt.Println("Numbers must be greater than 2 for this to work.") | |
| return nil | |
| } | |
| primes := []int{} | |
| for num1 <= num2 { | |
| isPrime := true | |
| for i := 2; i <= int(math.Sqrt(float64(num1))); i++ { | |
| if num1 % i == 0 { | |
| isPrime = false | |
| break | |
| } | |
| } | |
| if isPrime { | |
| primes = append(primes, num1) | |
