C++ Pointer Help

[kpb17]

I'm trying to figure out the value of pointers after the following code snippet

int s[8] ;

int *iptr1, *iptr2 ;

int **iptr3 ;

for (int i = 0 ; i < 8 ; i++)

s[i] = 7 - i ;

iptr1 = s ;

iptr2 = &s[3] ;

iptr3 = &iptr1 ;

*iptr1 = 5 ;

*iptr2 = 11 ;

**iptr3 = 14 ;

I neeed to find what the value of iptr1, iptr2, and iptr3 are after the code is executed. I'm having trouble understanding how pointers work, so any clarity on this would be appreciated. Thanks.

Why don't you give it a shot yourself first? Explain what you think each line means and what the value of each variable is. Then we'll tell you if it's correct and give you further advice.

Or, you could write a program and see what it does.

and step through the program using the debugger so that you can see the changes as they happen. Then hopefully you'll understand.
