Program to print the smallest element present in an array

Explanation

In this program, we need to find out the smallest element present in the array. This can be achieved by maintaining a variable min which initially will hold the value of the first element. Loop through the array by comparing the value of min with elements of the array. If any of the element's value is less than min, store the value of the element in min.

Consider above array. Initially, min will hold the value 25. In the 1st iteration, min will be compared with 11. Since 11 is less than 25. Min will hold the value 11. In a 2nd iteration, 11 will be compared with 7. Now, 7 is less than 11. So, min will take the value 7. Continue this process until the end of the array is reached. At last, min will hold the smallest value element in the array.

Algorithm

Declare and initialize an array.
Store first element in the variable min.
Loop through the array from 0 to length of the array and compare the value of min with elements of the array.
If any element is less than min, min will hold the value of that element.
At last, min will represent the smallest element in the array.

Input:

arr = [25, 11, 7, 75, 56]

Output:

Smallest element present in given array: 7

#Initialize array arr = [25, 11, 7, 75, 56]; #Initialize min with the first element of the array. min = arr[0]; #Loop through the array for i in range(0, len(arr)): #Compare elements of array with min if(arr[i] < min): min = arr[i]; print("Smallest element present in given array: " + str(min));

#include <stdio.h> int main() { //Initialize array int arr[] = {25, 11, 7, 75, 56}; //Calculate length of array arr int length = sizeof(arr)/sizeof(arr[0]); //Initialize min with first element of array. int min = arr[0]; //Loop through the array for (int i = 0; i < length; i++) { //Compare elements of array with min if(arr[i] < min) min = arr[i]; } printf("Smallest element present in given array: %d\n", min); return 0; }

public class SmallestElement { public static void main(String[] args) { //Initialize array int [] arr = new int [] {25, 11, 7, 75, 56}; //Initialize min with first element of array. int min = arr[0]; //Loop through the array for (int i = 0; i < arr.length; i++) { //Compare elements of array with min if(arr[i] < min) min = arr[i]; } System.out.println("Smallest element present in given array: " + min); } }

using System; public class SmallestElement { public static void Main() { //Initialize array int [] arr = new int [] {25, 11, 7, 75, 56}; //Initialize min with first element of array. int min = arr[0]; //Loop through the array for (int i = 0; i < arr.Length; i++) { //Compare elements of array with min if(arr[i] < min) min = arr[i]; } Console.WriteLine("Smallest element present in given array: " + min); } }
