Quick question about pointers

[MonaLisaO]

Hi I have a question about pointers:

int a = 10;
BOOL rc =  myMethod (struct_A, &a);

My method is like this:

BOOL myMethod (STRUCT aStruct, int* numElements)
{
  int temp = *numElements;
  *numElements = 0;
   ...
   return true;
}

Does temp == 10 or 0?

according to me, when u wrote following stement;
int temp = *numElements;
temp became equal to 10;
temp==10.
N after you wrote this statement;
*numElements = 0;
temp==0;
so recently its 0.

So then how do I give temp the value of numElements then change the value of numElements to 0?

temp is still 10, when you did *numElements = 0; only the variable "a" changed AFAIK.

Yaeh.
i was wrong. temp is still 10. I agree to that.

Ok, that is what I thought would happen.

Just a quick confirmation that between you you have got to the correct result

after the code has run (or just before it finishes running)

temp == 10

*numElements == 0

since numElements == &a
a also == 0
