    Address of variables?

    I was trying to figure this problem out. I know that if the address for each variable were not in this problem, i =14 j = 7 p=14 q=7...How does adding in the address for this program affect the output of the variables?




    Consider the program below. Fill in the values for variables 'i', 'j', 'p', 'q' after the
    code fragment has executed. The table below shows the address of each variable
    in memory (e.g. variable 'i' is stored at address 2000). For each answer, enter an integer left justified with no leading zeroes.

    Code:
    i:2000
    j:2004
    p:2008
    q:2012
    
    i:
    j:
    p:
    q:
    
    int i = 12, j = 14;
    int *p, * q;
    p = &i;
    q = &j;
    *p = *q;
    *q = 7;

    It doesn't change anything, it's just to help you visualise actual storage.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
