Golang program to calculate the area of the Rectangle

Program/Source Code:

The source code to calculate the area of the Rectangle is given below. The given program is compiled and executed successfully.

// Golang program to calculate the area of Rectangle

package main
import "fmt"

func main() {
    var length float32=0
    var breadth  float32=0
    var area  float32=0
    
    fmt.Printf("Enter length: ")
    fmt.Scanf("%f",&length)
    
    fmt.Printf("Enter breadth: ")
    fmt.Scanf("%f",&breadth)
    
    area = length * breadth

    fmt.Printf("Area of Rectangle: %f",area)
}

Output:

Enter length: 19
Enter breadth: 3.2
Area of Rectangle: 60.799999

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we read values for length and breadth from the user and calculated the area of the rectangle using the standard formula. After that printed the result on the console screen.
