Cpp program to display smallest number of an Array

Cpp program to display smallest number of an Array

In this tutorial, we will discuss the concept of Cpp program to display smallest number of an Array.

In this topic, we will learn how to find the smallest elements of array elements in Cpp programming language

This program gets “n” number of elements and Enter the elements of the array as input from the user. then, this program finds and displays the smallest elements from the array using for loops.

In this programs, we can see step by step procedure for completion of the program.

• array declaration
• Essential variable declaration
• Get input from the user for array length
• Get input from the user for array elements
• loop for finding the largest value
• Display result on the screen

Find smallest elements from integer Array

program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int arr[30]; //array declaration
    int length,i,min;//essential variable declaration
    cout << "Enter the length of the array: ";
    cin>>length;
    for(i=0; i<length; i++){
        cout<<"Enter elements "<<i+1<<" :";//enter elements for array
        cin>>arr[i];//store the element in array
    }
    min=arr[0];//assume the first elements as smallest number
    for(i=0; i<length; i++){
    if(min>arr[i]){
        min=arr[i];
    }
    }
    cout<<"\nsmallest elements is: "<<min;
    getch();//display result on the screen
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter the length of the array: 6

Enter element 1: 56
Enter element 2: 34
Enter element 3: 78
Enter element 4: 21
Enter element 5: 76
Enter element 6: 43
Smallest element is: 21

Find smallest elements from float Array

Program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    float arr[30],min; //array declaration
    int length,i;;//essential variable declaration
    cout << "Enter the length of the array: ";
    cin>>length;
    for(i=0; i<length; i++){
        cout<<"Enter elements "<<i+1<<" :";//enter elements for array
        cin>>arr[i];
    }
    min=arr[0];//assume the first elements as smallest number
    for(i=0; i<length; i++){
    if(min>arr[i]){
        min=arr[i];
    }
    }
    cout<<"\nsmallest elements is: "<<min;
    getch();display result on the screen
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter the length of the array: 6
Enter element 1: 34.2
Enter element 2: 54.1
Enter element 3: 8.5
Enter element 4: 23.5
Enter element 5: 47.6
Enter element 6: 51.3

smallest element is: 8.5
