//displays variable values
fmt.Printf("\n num1 : %d", num1)
fmt.Printf("\n num2 : %d ",num2)
//using math library functions
result := math.Max(float64(num1),float64(num2))
fmt.Print("\n Sum of two numbers : ",result)
result = math.Sqrt(float64(num1))
fmt.Print("\n Square Root of ",num1," is ",result)
fmt.Print("\n Before Swapping :")
fmt.Printf("\n num1 = %d",num1)
fmt.Printf("\n num2 = %d",num2)
//interchange values using call by reference
swap(&num1,&num2)
fmt.Print("\n After Swapping :")
fmt.Printf("\n num1 = %d",num1)
fmt.Printf("\n num2 = %d",num2)

}
