/*
Coding Exercise #1

    Using the var keyword, declare 4 variables called a, b, c, d of type int, float64, bool and string.

    Using short declaration syntax declare and assign these values to variables x, y and z:

    - 20

    - 15.5

    - "Gopher!"

    Using fmt.Println() print out the values of a, b, c, d, x, y and z.

    Try to run the program without error.

package main

import "fmt"

func main() {
	var a int
	var b float64
	var c bool
	var d string
	x := 20
	y := 15.5
	z := "Gopher!"

	fmt.Println(a, b, c, d)
	fmt.Println("X is", x, "\nY is", y, "\nZ is", z)
}
*/

/*
Coding Exercise #2

Change the code from the previous exercise in the following way:

1. Declare a, b, c, d using a single var keyword (multiple variable declaration) for better readability.

2. Declare x, y and z on a single line -> multiple short declarations

3. Remove the statement that prints out the variables. See the error!

4. Change the program to run without error using the blank identifier (_)

	_, _, _, _, _, _, _ = a, b, c, d, x, y, z
