For a better understanding of this example, we always recommend you to learn the basic topics of Golang programming listed below:
To add two arrays of numbers we have to traverse both the array simultaneously from the ent until the 0th index of either of the array. While traversing each element of both the array add the corresponding elements of both the array and store the result in another array.
Here we are showing to add two arrays in the Go language. Here variable size holds the size of the array, and other variables Arr1, Arr2 holds the arrays to be added. Variable sumArr holds the resultant array elements. First, read the array elements using for loop. Elements of both the arrays to be added is readed by using for loop.
syntax for for loop
for initializer; condition; incrementor {
}
After that add the two arrays as sumArr[i] = Arr1[i] + Arr2[i]. For traversing the arrays again for loop is used. The corresponding elements are added and the result is stored into sumArr. Finally, print the result array sumArr.Given below are the steps which are used in the Go program.
STEP 1: Import the package fmt
STEP 2: Start function main()
STEP 3: Read the size of the array using fmt.Scanfln()
STEP 4: Declare the arrays variable Arr1, Arr2, sumArr
STEP 5: Read the first array using for loop
STEP 6: Read the second array using for loop
STEP 7: Add the two arrays by adding sumArr[i] = Arr1[i] + Arr2[i]
STEP 8: Print the result array sumArr using fmt.Println()
package main
import "fmt"
func main() {
var size, i int
fmt.Print("Enter the array size = ")
fmt.Scanln(& size)
Arr1 := make([]int, size)
Arr2 := make([]int, size)
sumArr := make([]int, size)
fmt.Println("Enter the first array items = ")
for i = 0; i < size; i++ {
fmt.Scanln(& Arr1[i])
}
fmt.Println("Enter the second array items = ")
for i = 0; i < size; i++ {
fmt.Scanln(& Arr2[i])
}
fmt.Println("The sum of two arrays = ")
for i = 0; i < size; i++ {
sumArr[i] = Arr1[i] + Arr2[i]
fmt.Println(sumArr[i], " ")
}
fmt.Println()
}
Enter the array size = 5 Enter the first array items = 1 2 3 4 5 Enter the second array items = 6 7 8 9 10 The sum of two arrays = 7 9 11 13 15
