c++ - How to use array address to reverse an array? -

i understand array address code found in book made me nut.i understand recursive function did not one.here code:

int main(){   const int arraysize = 5;   int a[arraysize] = { 32, 27, 64, 18, 95};    cout << "the values in reverse  array are:" << endl;   somefunction(a, arraysize);   cout << endl;   cin.get();   return 0; }  void somefunction(int b[], int size) {   if (size > 0) {      somefunction(&b[1], size - 1);      cout << b[0] << " ";    } } 

i got code in exercise.my question how reversing array?i happy if explain bit more.thanks

here pseudo-code shows how recusive calls somefunction made, , in order:

somefunction( { 32, 27, 64, 18, 95} , 5) somefunction( { 27, 64, 18, 95}, 4) somefunction( { 64, 18, 95}, 3) somefunction( { 18, 95}, 2) somefunction( { 95}, 1) somefunction( { }, 0) 

somefunction({ }, 0) return without doing because there nothing left in array. somefunction print first element b[0] of arrays comes out of recursion, beginning array containing 1 item {95}:

{ 95 } { 18, 95} { 64, 18, 95} { 27, 64, 18, 95} { 32, 27, 64, 18, 95} 

so output be:

"the values in reverse  array are:" 95 18 64 27 32
