sizeof array problem

Here's the code:


#include <stdafx.h>
#include <iostream>
#include <iomanip>
using namespace std ;

void outputSize( int vals [] )
{
      cout << "In outputSize():  {" << sizeof(vals)/sizeof(vals[0]) << "}" << endl ;
}

int main()
{
      int vals [] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 } ;

      // output array size
      cout << "In main():  {" << sizeof(vals)/sizeof(vals[0]) << "}" << endl ;
      
      // pass array to function, where it's size should be outputted
      outputSize( vals ) ;

      return 0 ;
}


And here's the output:

  In main():  {10}
  In outputSize():  {1}


For some reason, it would seem that 'sizeof(vals)' in the outputSize() function is getting the sizeof a single element within the array, rather than the total amount of memory occupied by the entire array...

- Why is this?
- How can I solve it?


Thanks
