Cpp program to find largest elements of an Array

In this tutorial, we will discuss the small concept of Cpp program to find the largest elements of an Array.

In this topic, we will learn how to find the largest 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 largest 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 largest value
Display result on the screen

Find largest elements from integer Array

Program 1

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

int main()
{
    int arr[30];//array declaration
    int length,i, max; //essential variable declaration
    cout<<"Enter the length of the array: ";
    cin>>length;//get input from user for length
    for(i=0; i<length; i++){
    cout<<"Enter element "<<i+1<<" :";//enter elements for array
    cin>>arr[i];
    }
    max=arr[0];

    for(i=0; i<length; i++){
    if(max<arr[i]){
        max=arr[i];
    }
    }
    cout<<"\nlargest elements is:"<<max;
getch();
    return 0;
}

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

Enter the length of the array: 5
Enter element 1:87
Enter element 1:65
Enter element 1:78
Enter element 1:43
Enter element 1:56

largest element si: 87

Find largest elements from float Array

Program 2

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

int main()
{
    float array[100];//Array declaration
    int length,i;
    double max;//variable declaration
    cout << "Enter the length of the array: " << endl;
    cin>>length;//Takes input from user for length
    for(i=0; i<length; i++){
        cout<<"Enter element "<<i+1<<" :";//enter elements for array
        cin>>array[i];
    }
    max=array[0];
    for(i=0; i<=length; i++){
        if(max<array[i]){
            max=array[i];
    }
}
cout<<"\n Largest elements is: "<<max;
getch();
    return 0;
}

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

Enter the length of the array:
5
Enter element 1 :4.6
Enter element 1 :3.7
Enter element 1 :7.9
Enter element 1 :9.8
Enter element 1 :3.2

Largest elements is: 9.8
