In this we discussed about how to find the smallest element in the array with some approaches and you can also do with more approaches 


the below points mentions we discussed in this article


  • Question
  • sample input
  • Logic
  • solution with loop
  • solution using function
  • Feedback

Question-

  C++ program to print the smallest element in an array



C++ program to print the smallest element in an array



sample input 


enter the range - 4

2 4 6 3

The smallest element is

2


Logic to solve the problem

  • Take an array of some integers then take a variable ( n )  for taking the input how many data the user want to enter then run a for loop to taking the inputs . 
  • Again run another for loop and inside the loop use if condition for checking the small element in the array , Take a variable for comparing the small element,.
  • Then check inside the if the condition that the value that is smaller than that assign it to small and print the small value
  • Then again run a for loop to displaying the array after reversing.

Source Code

#include<iostream>
using namespace std;
int main()
{
    int n,small;
    cout<<"Enter the size :"<<endl;
    cin>>n;
    int arr[100];
    for(int i=0;i<n;i++)
    {
        cout<<"Enter the element no."<<i+1<<" :";
        cin>>arr[i];
    }
    for(int i=0;i<n;i++)
    {
        if(small>arr[i])
        small=arr[i];
    }
    cout<<"The smallest elemnt in the array is :"<<small;
   return 0;
}




Solve by using the function


Source Code


// Write a C++ program to find the smallest element of a given array of integers
#include <iostream>
using namespace std;

void small(int arr[], int n)
{
    int smalll;
    for (int i = 0; i < n; i++)
    {
        if (smalll < arr[i])
            smalll = arr[i];
    }
    cout << "The smallest element in the array is :" << smalll;
}
int main()
{
    int n;
    cout << "Enter the size :" << endl;
    cin >> n;
    int arr[100];
    for (int i = 0; i < n; i++)
    {
        cout << "Enter the element no." << i + 1 << " :";
        cin >> arr[i];
    }
    small(arr, n);
    return 0;
}
