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 (_)
