how come an additional number is printed: the size 3? see my code below

Question

int printarray(int arr[], int size)
{
for(int x=0; x<size; x++)
{
cout <<arr[x]<< endl;
}
}

int main ()
{
int myarr[]={53, 99, 505};
cout <<printarray(myarr, 3);/*output:
53
99
505
3
*/
}

Answer 1

printarray() has a 'cout ...' line and you have another 'cout ...' in main(), that could be the reason
