Why isn't my array printing the correct output?(even numbers from 0-50)

[Givi]

I'm using a function to find all the even numbers from an array, ranging from 0-50. Without using a function, it's very simpple. However, using size = 50; I'm not getting the expected outcome.

#include <iostream>
using namespace std;
void arrayFill(int evenArray[], int size);
int main()
{

    int size = 50;
    int evenArray[size];
    
    arrayFill(evenArray, size);
    
    return 0;
}

void arrayFill(int evenArray[], int size)
{
    for (int i = 0; i <= size; i = i + 2)
    {
        cout << evenArray[i] << endl;
    }
} 

The output is:

1971728815
8
2006565836
-1
2686564
12
2686648
3670016
1971728815

2006565836
-1
2686628
0

1971732984
-819286188
4199104
4200976
16
1971810848

When it should be
2
4
6
....
50

You don't initialize your array so it just contains random numbers.
You access your array out of bounds for (int i = 0; i <= size; i = i + 2).
The last element is size - 1
