What does the following program do? Explain it and print the screen-shot.

#include <iostream> using namespace std; int whatIsThis( int [ ], int ); // function prototype int main( ) { const int arraySize = 10; int a[ arraySize ] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; int result = whatIsThis( a, arraySize ); cout << "Result is " << result << endl; return 0; } // end main // What does this function do? int whatIsThis( int b[], int size ) { if ( size == 1 ) // base case return b[ 0 ]; else // recursive step return b[ size - 1 ] + whatIsThis( b, size - 1 ); } // end function whatIsThis
