Conditionals

if statements in Go do not use parentheses around the condition:

if height > 4 {
    fmt.Println("You are tall enough!")
}

else if and else are supported as you might expect:

if height > 6 {
    fmt.Println("You are super tall!")
} else if height > 4 {
    fmt.Println("You are tall enough!")
} else {
    fmt.Println("You are not tall enough!")
}

Unlike other languages, you must put the opening brace on the same line as the condition and not on a new line.

Assignment

Fix the bug on line 12. If messageLen is less than or equal to the maxMessageLen the program should print "Message sent", else it should print "Message not sent".

  • == equal to
  • != not equal to
  • < less than
  • > greater than
  • <= less than or equal to
  • >= greater than or equal to
