For a better understanding of this example, we always recommend you to learn the basic topics of Golang programming listed below:
For finding the largest item among the array element, we have to traverse the array frm the initial position to the final. First, assume that the first array item is the largest item. Hold this first element as thge largest element in a variable. Increment the array position and compare the secdond item with the current highest element. if the second element is larger than the present largest element then save this second element to the variable holding the largest and save its position to another variable.continue this procedure till to the last element.
Here we are showing how to find the largest array item in the Go language. Here variable size holds the size of the array, and other variable Arr holds the array elements. First, read the array elements using for loop.
syntax for for loop
for initializer; condition; incrementor {
}
After reading the elements, traverse the array from the beginning using a for loop. First, assign the first array item as the largest value. Using if condition ( largest < Arr[i]) check whether the current array item is less than the largest element . If true, assign that element to the largest, and put the index value in the pos variable.
syntax if condition
If condition {
//perform some instruction
}
Finally, print the largest element and it's position.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 variables i, pos,largest, and array Arr
STEP 5: Read the array using for loop
STEP 6: First assign Arr[0] to largest
STEP 7: Using for loop find the largest element and its position
STEP 8: Use if to check largest < Arr[i]
STEP 9: If true assign largest = Arr[i] and pos = i continue loop untill i reaches the size
STEP 9: Print the largest element and its position using fmt.Println()
package main
import "fmt"
func main() {
var size, i, pos int
fmt.Print("Enter the array size to find largest = ")
fmt.Scan(& size)
Arr := make([]int, size)
fmt.Print("Enter the array items = ")
for i = 0; i < size; i++ {
fmt.Scan(& Arr[i])
}
largest := Arr[0]
for i = 0; i < size; i++ {
if largest < Arr[i] {
largest = Arr[i]
pos = i
}
}
fmt.Println("\nThe largest number in this Arr = ", largest)
fmt.Println("The index position of largest number = ", pos)
}
Enter the array size to find largest = 4 Enter the array items = 20 35 45 17 The largest number in this Arr = 45 The index position of largest number = 2
