Solution Review: Season of a Month

Explore how to determine the season based on month input in Go using both switch-case and if-else control structures. Understand how to handle valid month values for all seasons and manage edge cases where input is invalid, helping you master decision-making in Go programming.

We'll cover the following...

There are two methods to solve this problem:

  • One is using the switch-case construct, which is the requirement of the problem statement
  • The other is using the if-else construct.

We’ll first discuss the switch-case solution.

Using switch-case construct

Go (1.6.2)
package main
import "fmt"
func main() {
	fmt.Printf(Season(3))     // calling function to find the season
}
func Season(month int) string {
	switch month {  // switch on the basis of value of the months(1-12)
		case 12,1,2:  return "Winter"  // Jan, Feb and Dec have winter
		case 3,4,5:	  return "Spring"  // March, Apr and May have spring
		case 6,7,8:   return "Summer"  // June, July and Aug have summer
		case 9,10,11: return "Autumn"  // Sept, Oct and Nov have autumn
		default: return "Season unknown"         //value outside [1,12], then season is unkown
	}
}

As you can see, we declare a function Season at line 9, which takes an integer value that represents a month as an input parameter. That parameter is the value of month. As per requirement, we add ...
