GO Program to search for array items

How to search items of array 

Here we are explaining how to search array items in the Go program. We can use the built-in function fmt.println() to print anything and fmt.scanln() for reading the values. This function is defined under the fmt package and it helps to write standard output. In order to use these functions, we need to import the “fmt” package.


How to search items of array in the GO Program

We are using fmt.println() function for printing the string to the output screen. Here we are showing how to search items of array in the Go language. Here variable Arr holds the array elements. Other variables size, search used as size of the array and search element. First, set flag with zero. Use for loop to find the index position of the element and iterate through the loop. If (Arr[i] == search) then flag=0 means that searched element is find also take i as index position. Finally, check flag=0 if true we find the element otherwise not found. 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: Declare the variable search,size,flag,i

STEP 4: Read the array Arr[] using for loop

STEP 5: Search for the item in a for loop as  if (Arr[i] == search)

STEP 6: If matched set flag as flag = 0

STEP 7:Print the index position using fmt.Println()


GO Source Code

                                          package main
import "fmt"

func main() {
    var size, i, search int
    fmt.Print("Enter the array size = ")
    Arr := make([]int, size)
    fmt.Print("Enter the array items  = ")
    for i = 0; i < size; i++ {
    fmt.Print("Enter the search item  = ")
    flag := 0
    for i = 0; i < size; i++ {
        if Arr[i] == search {
            flag = 1
    if flag == 1 {         fmt.Println("Search item ", search, " at positiNot found the search item ")


Enter the array Size = 5
Enter the array items  = 10 20 30 40 50
Enter the search item  = 40 Search item  40  at positi
