I read the following points related to side effects in gnu c manual it is necessary for the following points to hold true between two sequence points:
1.an object may have its stored value modified at most once by the evaluation of an expression
2.the prior value of the object shall be read only to determine the value to be stored.
I am not able to understand the 2 point ..Can someone please explain it with an example..it would be very helpful...
