Multiplications of array in C++/C

 Write a simple program Multiplications of array in C++/C

#include <iostream>

using namespace std;

void display(int *arr, int n)

{

    for (int i = 0; i < n; i++)

    {

        cout << arr[i] << " ";

    }

    cout << endl;

}

int multiplyofArray(int arr[], int n)

{

    int multi = 1;

    for (int i = 0; i < n; i++)

    {

        multi *= arr[i];

    }

    return multi;

}

int main()

{

    int arr[] = {1, 2, 3, 4, 5};

    int n = sizeof(arr) / sizeof(int);

    cout << "The array is : ";

    display(arr, n);

    cout << "The Multiply array : " << multiplyofArray(arr, n) << endl;

}

Output is :

The array is : 1 2 3 4 5 The Multiply array : 120
