/*
Coding Exercise #1

Consider the following variable declarations:

    x, y, z := 10, 15.5, "Gophers"
    score := []int{10, 20, 30}

Using fmt.Printf():

    Print each variable using a specific verb for its type

    Print the string value enclosed by double quotes ("Gophers")

    Print each variable using the same verb

    Print the type of y and score

package main

import "fmt"

func main() {
	x, y, z := 10, 15.5, "Gophers"
	score := []int{10, 20, 30}

	fmt.Printf("x is %d, y is %f, z is %s\n", x, y, z)
	fmt.Printf("score is %#v\n", score)
	fmt.Printf("Values are %v,%v,%v,%v \n", x, y, z, score)
	fmt.Printf("y is %T\nscore is %T\n", y, score)
}
*/

/*
Coding Exercise #2

Consider the following constant declaration: const x float64 = 1.422349587101

Write a Go program that prints the value of x with 4 decimal points.

package main

import "fmt"

func main() {
	const x float64 = 1.422349587101
	fmt.Printf("%.4f\n", x)
}
*/

/*
Coding Exercise #3

There are some errors in the following Go program. Try to identify the errors, change the code and run the program without errors.

    package main

    import "fmt"

    func main() {
    	shape := "circle"
    	radius := 3.2
    	const pi float64 = 3.14159
    	circumference := 2 * pi * radius

    	fmt.Printf("Shape: %q\n")
    	fmt.Printf("Circle's circumference with radius %d is %b\n", radius, circumference)
    	_ = shape
    }
*/
package main

import "fmt"

func main() {
	shape := "circle"
	radius := 3.2
	const pi float64 = 3.14159
	var circumference float64 = float64(2) * pi * radius

	fmt.Printf("Shape: %q\n", shape)
	fmt.Printf("Circle's circumference with radius %f is %f\n", radius, circumference)
}
