Exercise 1 :

/tmp/sandbox760491916/main.go:6: syntax error: unexpected semicolon or newline before {

Needed to push the start parenthesis to the line contain main(). After that it gave the obvious errors i.e.
- package "os" is imported but not used
- println - cannot refer to unexported name fmt.println

Exercise 5: http://play.golang.org/p/MghgrHkxqj

Exercise 6: Since there is no expression in the switch statement, it defaults to boolean. So the first block that evaluates to true is considered. And in this case it is the case true : fmt.Println("I am true")

Exercise 7: The switch statement expression is an int. However one of the case statements evaluates to a boolean value i.e. i>8, hence it does not compile.
