How to find the sum of array items?

To Find the sum of the array elements we have to add all the elements in the array. Here we have to read the values and add that to our array. Set a variable s=0 initially to hold the sum. Then traverse the array from the first position. Add the first element with 's' and store the current value in s. Continue the procedure with all elements. Finally, we get the sum from the variable s.

How to add all the array elements in the Go Program?

In this Go program, to add all the elements in an array, we have to declare an array variable Arr. declare other variables Sum, i used as result and index variables. Use for loop to find the sum of elements from i=0 to i less than the size of the array. After that add the array elements as Sum = Sum + Arr[i] in a loop. Finally, print the result.

ALGORITHM

STEP 1: Import the package fmt

STEP 2: Start function main()

STEP 3: Declare the variable Sum, i

STEP 4: Define the array Arr[] with 5 elements and Sum=0

STEP 5: Start a for loop for adding array elements from i=0 to i

STEP 6: Find the sum as Sum = Sum + Arr[i]

STEP 7:Print the result Sum using fmt.Println()


To find the sum of array elements we have to know the below GO programming concepts, we recommend you to learn those for a better understanding

Golang Source Code

                                          package main
import "fmt"

func main() {
    Arr := []int{5, 10, 15, 20, 25}
    Sum := 0
    for i := 0; i < len(Arr); i++ {
        Sum = Sum + Arr[i]
    }
    fmt.Println("The sum of array items = ", Sum)
}
                                      

OUTPUT

The sum of array items =  75
