# Multiple Return Values in Go  ## Go: Multiple Return Values

One of the key features of Go is its ability to return multiple values from a single function. This feature enables Go developers to write cleaner and more concise code, which can be more readable and easier to maintain.

In this article, we will explain multiple return values in Go with a simple example. We will start by providing a brief overview of Go's return values and then proceed to walk you through a practical example.

### What are Multiple Return Values in Go?

Multiple return values in Go are simply a way of returning multiple values from a single function. This feature is particularly useful when you want to return multiple results from a function, such as the results of a calculation or the values of multiple variables.

In Go, multiple return values are specified by including multiple variables in the return statement. For example, if you have a function that calculates the area and perimeter of a rectangle, you can return both values as follows:

``````
func rectangle(length, width int) (area int, perimeter int) {
area = length * width
perimeter = 2 * (length + width)
return
}

``````

In this example, the function `rectangle` calculates the area and perimeter of a rectangle, and returns both values. To retrieve these values, you can simply call the function and assign the returned values to variables:

``````
a, p := rectangle(10, 5)
fmt.Println("Area:", a)
fmt.Println("Perimeter:", p)

``````

### An Example of Multiple Return Values in Go

Now that we have a basic understanding of multiple return values in Go, let's walk through a practical example to see how they can be used.

Suppose we have a function that takes a list of integers and returns the minimum and maximum values in the list. To implement this function, we can use multiple return values as follows:

``````
func minMax(numbers []int) (min int, max int) {
min = numbers
max = numbers
for _, n := range numbers {
if n < min {
min = n
}
if n > max {
max = n
}
}
return
}

``````

In this example, the function `minMax` takes a list of integers and calculates the minimum and maximum values in the list. To retrieve these values, you can simply call the function and assign the returned values to variables:

``````
numbers := []int{1, 2, 3, 4, 5}
min, max := minMax(numbers)
fmt.Println("Minimum:", min)
fmt.Println("Maximum:", max)

``````

### Conclusion

Multiple return values are a useful feature of Go that enables developers to write cleaner and more concise code. By using multiple return values, you can simplify your code and make it easier to understand, maintain, and debug.

Whether you're just starting out with Go or you're an experienced developer, we hope this article has helped you gain a deeper understanding of multiple return
