Find Largest Element in an Array


Write a C++ Program to find Largest Element in an Array. Here’s simple Program to find Largest Element in an Array in C++ Programming Language.


What is an Array ?


Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

Instead of declaring individual variables, such as number0, number1, …, and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and …, numbers[99] to represent individual variables. A specific element in an array is accessed by an index.

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.


Here is source code of the C++ Program to find Largest Element in an Array. The C++ program is successfully compiled and run on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/*  C++ Program to find Largest Element in an Array  */

#include<iostream>

using namespace std;

int main()
{
    int i,a[50],size;
    cout<<"Enter array size( Max:50 ) :: ";
    cin>>size;
        cout<<"\nEnter array elements :: \n";

        for(i=0; i<size; i++)
        {
            cout<<"\nEnter arr["<<i<<"] Element :: ";
                cin>>a[i];
        }

  cout<<"\nStored Data in Array :: \n\n";

  for(i=0;i<size;i++)
  {
  cout<<" "<<a[i]<<" ";
  }

    int  largest=a[0];

        for (i=0;i<size;i++)
    {
                if(a[i]>largest)
                {
                        largest=a[i];
                }
        }
        cout<<"\n\nLargest Element in an Array :: "<<largest<<endl;

        return 0;
}

OUTPUT : :


/*  C++ Program to find Largest Element in an Array  */

Enter array size( Max:50 ) :: 8

Enter array elements ::

Enter arr[0] Element :: 4

Enter arr[1] Element :: 1

Enter arr[2] Element :: 3

Enter arr[3] Element :: 2

Enter arr[4] Element :: 5

Enter arr[5] Element :: 7

Enter arr[6] Element :: 9

Enter arr[7] Element :: 0

Stored Data in Array ::

 4  1  3  2  5  7  9  0

Largest Element in an Array :: 9

Process returned 0

Above is the source code for C++ Program to find Largest Element in an Array which is successfully compiled and run on Windows System.The Output of the program is shown above .

Thanks, can you post for the smallest one as well?

thesk

int smallest = arr[0];
    for (i = 0; i < size; i++) {
        if (arr[i] < smallest) {
            smallest = arr[i];
        }
    }

This is the requried logic for finding smallest element

Yes
