Two ways to make a variable

Goal

Fill in two small functions. Greeting makes a box with var and returns it. Visits makes a box with := and returns it.

Example

If a function were meant to return the city "Lisbon", you would write:

func City() string {
	var city string = "Lisbon"
	return city
}

The variable is declared first, and the return line hands back what is in the box.

Rules

• Edit declare.go. Each function has a // TODO comment and a return line you will change.
• In Greeting, declare a variable with var, give it the type string and the value "Hello", and return it.
• In Visits, declare a variable with := holding the whole number 3, and return it.
• The function names and what they return are fixed. Do not change the lines func Greeting() string { and func Visits() int {.
• Do not add imports. You will not need any.
• Remember that := only works inside a function, which is exactly where you are.

What you'll practice

Declaring a variable with var, declaring one with :=, and returning it.

cd 08-01-declare-with-var-and-short
gonomicon test

Hints

1. You need one box made with var and one made with :=. Each function makes its box, then returns it.
2. var greeting string = "Hello" spells out the type. visits := 3 lets Go work out the type. Replace the return line in each function so it returns your variable.
3. Greeting: var greeting string = "Hello" then return greeting. Visits: visits := 3 then return visits.
