reversing an array

-
#include <iostream>
using namespace std;

void reverse(int arr[],int size){
int start = 0;
int end = size-1;

while (start<=end)
{
swap(arr[start],arr[end]);
start++;
end--;

}
}


void printingarr(int arr[],int size){
for (int i = 0; i < size; i++)
{
cout<<arr[i]<<" ";
}
}
int main(){

int arr[10]= {23,43,65,3,2,366,43,74,32,64};

reverse(arr,10);
printingarr(arr,10);
