```
#include

using namespace std;

void printArray( const int [], int, int );

int main()
{
const int SIZE = 10;
const int MAXNUMBER = 500;
int array[ SIZE ];

srand( time( 0 ) );

// initialize array elements to random numbers
for ( int loop = 0; loop < SIZE; loop++ )
array[ loop ] = 1 + rand() % MAXNUMBER;

cout << "Array values printed in main:\n";

for ( int j = 0; j < SIZE; j++ ) // print array elements
cout << setw( 5 ) << array[ j ];

cout << "\n\nArray values printed in printArray:\n";
printArray( array, 0, SIZE - 1 );
cout << endl;
} // end main

void printArray( const int array[], int low, int high )
{
// print first element of array passed
cout << setw( 5 ) << array[ low ];

// return if array only has 1 element
if ( low == high )
return;
else // recursively call printArray with new subarray as argument
printArray( array, low + 1, high );
} // end function printArray
```
Array values printed in main:
465 117 93 285 373 172 472 439 455 31
Array values printed in printArray:
465 117 93 285 373 172 472 439 455 31
