Exercise 2

Question

Write a program that defines a string variable called message with the value "Hi 👩 and 👨" and prints the 4th rune in it as a character, not a number.

Solution

This question covers type conversions with strings and runes, as well as the zero-based offset for slices. You need to convert the message string to a []rune using a type conversion. Then you get the 4th rune in the rune slice using runes[3]. Finally, you need to use a string type conversion to convert the rune back into a character.
