Calculating the sum of all array elements in Golang

Problem Solution:

In this program, we will create an array of integers and calculate the sum of array elements. After that print the result on the console screen.

Program/Source Code:

The source code to calculate the sum of all array elements is given below. The given program is compiled and executed successfully.

Golang code to calculate the sum of all array elements

// Golang program to calculate the sum of all array elements

package main

import "fmt"

func main() {
	var sum int = 0
	arr := [...]int{1, 2, 3, 4, 5}

	for i := 0; i <= 4; i++ {
		sum = sum + arr[i]
	}

	fmt.Println("Sum of array elements is: ", sum)
}

Output:

Sum of array elements is:  15

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 created and initialized an array of integers. After that, we calculated the sum of all array elements and printed the result on the console screen.
