cpp reference array

// C++ Program to demonstrate Above Approach
 
// Importing input output stream to take input
// and to display anything on the console
#include <iostream>
 
using namespace std;
 
// Method 1
// To print array elements
void print(int arr[], size_t n)
{
 
    // Iterating over elements on an array
    // using the foreach loop
    for (int element : arr) {
        // Print the elements of the array
        cout << element << " ";
    }
 
    // New line as all the desired elements are printed
    cout << endl;
}
 
// Method 2
// Main driver method
int main()
{
    // Declaring and initializing Integer array with
    // custom input entries
    int a[]{ 1, 2, 3, 4 };
 
    size_t size = sizeof(a) / sizeof(a[0]);
 
    // Calling the Method1 as created above
    // in the main) method to
    // print array elements
    print(a, size);
}

#include <stdio.h>
#include <string.h>
