For a better understanding of this example, we always recommend you to learn the basic topics of Golang programming listed below:
Variable is a value that may change depending on certain condition or on information passed to the program.
Go lang variables can be defined as a piece of storage containing data temporarily to work with it.
Generally a variable in Go lang uses the keyword var
, explicit type and an assignment. The variables are declared with the desired name and the type of value that it will hold.
We are using fmt println()
function for printing the string to the output screen. Here we are showing how to print and declare different types of variables in the Go language. Here variables strs, strc is a string variable and intx, inty, intb is an integer variable and blna is a boolean variable. Given below are the steps which are used in the Go program.
STEP 1: Import the package fmt
STEP 2: Start function main()
STEP 3: Initialise string variable s with value "first" and print using fmt.println()
STEP 4: Initialise integer variable intx, inty with values "5,7" and print using fmt.println()
STEP 5: Initialise boolean variable blna with value "true" and print using fmt.println()
STEP 6: Declare integer variable intb and print using fmt.println()
STEP 7: Initialise string variable strc with value "second" and print using fmt.println()
package main
import "fmt"
func main() {
var strs = "first"
fmt.Println(strs)
var intx, inty int = 5, 7
fmt.Println(intx, inty)
var blna = true
fmt.Println(blna)
var intb int
fmt.Println(intb)
strc:= "second"
fmt.Println(strc)
}
first 5 7 true 0 second
