Q. Write a program to find smallest element in an array.



For Example :-
input : arr[]={ 8, 9, 1, 2, 4 }
output : 1

So as we can see that the smallest element in arr[] = {8, 9, 1, 2, 4 } is 1 so the output is 1.

Smallest element in an array algorithm

START
Step 1 → Take an array Arr and define its values
Step 2 → Declare one variable (VAR) and assign 1st element of array to it
Step 3 → Loop for each value of Arr Repeat Step 4
Step 4 → If Arr[I] < VAR, Assign Arr[I] to VAR
Step 5 → After loop finishes, Display VAR which holds the smallest element of array
STOP


Smallest element in an array program

  • C
  • C++
  • Java
  • Python
  • C#
  • PHP
    • #include <stdio.h>
int main() {
int i, arr[5]={ 7, 9, 1, -15, 0};
int VAR = arr[0];
for (i = 1; i < 5; ++i) {
if (VAR > arr[i])
VAR = arr[i];
}
printf("Smallest element in an Array is = %d", VAR);
return 0;
}

    #include <iostream>
using namespace std;
int main()
{
int i, arr[5]={ 7, 9, 1, -15, 0};
int VAR = arr[0];
for(i = 1;i < 5; ++i)
{
if(VAR > arr[i])
VAR = arr[i];
}
cout << "Smallest element in an Array is = " << VAR;
return 0;
}

    public class LFC {
public static void main(String[] args) {
int[] numArray = { 7, 9, 1, -15, 0};
int smallest = numArray[0];
for (int num: numArray) {
if(smallest > num)
smallest = num;
}
System.out.format("Smallest element in an Array is = %d", smallest);
}
}

    number = [7, 9, 1, -15, 0]
smallest_number = min(number);
print("Smallest element in an Array is = ", smallest_number)

    using System;
class LFC
{
static void Main()
{
int i       = 0;
int small   = 0;
//array declaration
int[] arr = {7, 9, 1, -15, 0};
//reading array elements 
//assigning first element to the array
small = arr[0];
//loop to compare value of small with other elements
for (i = 1; i < 5; i++)
{
//if small is smaller than other element
//assig that element to the small
if (small > arr[i])
small = arr[i];
}
//finally, we will have smallest element, printing here
Console.WriteLine("Smallest element in an Array : " + small);
}
}

    // Returns maximum in array 
function getMin($arr)  
{ 
$n = count($arr);  
$min = $arr[0]; 
for ($i = 1; $i < $n; $i++)  
if ($min > $arr[$i]) 
$min = $arr[$i]; 
return $min;        
} 
// Driver code 
$arr = array(7, 9, 1, -15, 0); 
echo "Smallest element in an Array : ";
echo(getMin($arr)); 

    #include <stdio.h>
int main() {
int i, arr[5]={ 7, 9, 1, -15, 0};
int VAR = arr[0];
for (i = 1; i < 5; ++i) {
if (VAR > arr[i])
VAR = arr[i];
}
printf("Smallest element in an Array is = %d", VAR);
return 0;
}

    Output

    Smallest element in an Array is = -15
