- - - - Subtraction
        
        b-a will be 1
        
        int a[] {1, 2, 3}; int *b = a; b++;
      - Addition
        
        int a[] {1, 2, 3}; int *b = a + 2;
        
        *b will be 3
- - - - A sequence point is a point in time at which the dust has settled and all side effects which have been seen so far are guaranteed to be complete
      - The sequence points listed in the C standard are
        
        At the end of the evaluation of a full expression
        
        A full expression is an expression statement, or any other expression which is not a subexpression within any larger expression
        
        At the ||, &&, ?:, and comma operators
        
        At a function call (after the evaluation of all the arguments, and just before the actual call)
      - Between the previous and next sequence point an object shall have its stored value modified at most once by the evaluation of an expression
      - The prior value shall be accessed only to determine the value to be stored
