GO Program to Calculate Area of Rectangle and Square
Check the scope of variable declare outside the main function and (l,b) both variables declare in a single statement. In this example, we are calculating are of rectangle and square.
Example
package main
import "fmt"
var area int // Variable declare outside the main function
func main(){
var l,b int //Declaration of multiple Variables
fmt.Print("Enter Length of Rectangle : ")
fmt.Scan(&l)
fmt.Print("Enter Breadth of Rectangle : ")
fmt.Scan(&b)
area = l * b
fmt.Println("Area of Rectangle : ",area) //move to new line
fmt.Print("Enter Length of Square : ")
fmt.Scan(&l)
area = l*l
fmt.Print("Area of Square : ",area)
}
