Write a C++ Program For Find Largest Element of an Array

#include <iostream>

using namespace std;

int main(){

    int i,n;

    float arr[100];

    cout << "Enter total number of elements: ";

    cin >> n;

    cout << endl;

    while (n>100 || n<=0)

    {

        cout << "Error! number should in range of (1 to 100)." << endl;

        cout << "Enter the number again: ";

        cin >> n;

    }

    for(i=0;i<n;++i)  /* Stores number entered by user. */

    {

       cout << "Enter Number " << i+1 << " : ";

       cin >> arr[i];

    }

    for(i=1;i<n;++i)  /* Loop to store largest number to arr[0] */

    {

       if(arr[0]<arr[i]) /* Change < to > if you want to find smallest element*/

           arr[0]=arr[i];

    }

    cout << "Largest element = " << arr[0];

    return 0;

}

Output

Enter total number of elements: 8

Enter Number 1: 23.4

Enter Number 2: -34.5

Enter Number 3: 50

Enter Number 4: 33.5

Enter Number 5: 55.5

Enter Number 6: 43.7

Enter Number 7: 5.7

Enter Number 8: -66.5

Largest element = 55.5
