Practice: switch and goto

The following exercises let you explore switch statements and goto.

1. Rewrite exercise 1 using a switch statement. Which version do you find more readable? Why?

2. The following code should break out of the for loop when i == 5, but it doesn’t. Why not? Identify the cause and fix it:

go for i:= range 10 { switch i { case 5: break default: fmt.Println(i) } }

3. Rewrite the code in the exercises/ex9 directory to use goto. Is it easier or harder to follow now? Why?
