8. A variable named widgets is stored in memory location 13571. When the statements |
|
|
|
|
|
|
|
|
widgets = 23;
Drop(widgets); |
|
|
|
|
|
|
|
|
are executed, what information is passed to the formal parameter in function Drop? (Assume the formal parameter is a reference parameter.) |
|
|
|
|
|
|
|
|
9. Assume that, in Exercise 8, the formal parameter for function Drop is named clunkers. After the function body performs the assignment |
|
|
|
|
|
|
|
|
clunkers = 77; |
|
|
|
|
|
|
|
|
what is the value in widgets? in clunkers? |

#include <iostream.h>
void Test( int&, int&, int& );
int main()
{
int a;
int b;
int c;
Test(a, b, c);
